[13:00] I guess I don't understand that yet. [13:00] xen isn't like virtualbox? [13:00] the first dom0 is sepcial in that it by default provides the network/disk for vm's. [13:01] xen is not like virtualbox [13:01] xen is like vmware esx [13:01] apparently it can actually pass that stuff onto to other vm's. [13:01] brycec: it's not quite like either of them really. [13:01] well it's more like esxi. [13:01] Yeah, ther's a term for it, I can't seem to recall [13:01] something about layers [13:01] so you have a hypervisor that runs a series of virtual machines, but the first one gets "direct" access. [13:02] and it then has a memory window or such to pass data to other virtual machines for disk/network. [13:02] Ah here we go https://en.wikipedia.org/wiki/Hypervisor [13:02] i wonder if i'm making it sound more complicated. [13:02] Hypervisor :: A hypervisor or virtual machine monitor (VMM) is a piece of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor is running one or more virtual machines is defined as a host machine. Each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating... [13:03] Yeah, dom0 is technically a vm but it's treated special. It's similar, but not identical to the way esx works with having a base OS+Hypervisor [13:03] brycec: well esxi runs linux .. [13:03] you can actually get a linux shell [13:03] * brycec knwos [13:03] so it may actually be quite similar, i haven't really looked uunder the hood much [13:04] it has very limited drivers unlike linux [13:04] you can't even do software raid with esxi (grr) [13:04] For the sake of simplicity and explaining things to RandalSchwartz... [13:04] so if you want a test server it's kind of annoying. [13:04] brycec: true. [13:04] ok yeah, it's like sxi :) [13:04] esxi [13:05] btw: vmware is currently getting sued for violating the gpl in esxi [13:05] you can actually host a virtual machine inside esxi that provides storage to esxi. [13:05] ant: makes sense. [13:05] virtualception [13:06] people were doing solaris/opensolaris/etc with zfs inside a virtual machine, then doing nfs from that for the esxi data store. [13:06] so I could run xen on my freebsd box, and use linux for the first vm, and freebsd for the other ones? [13:06] using vt-d to pass through a scsi controller generally, but i don't think that part is /necessary/ it just improves performance. [13:06] Probably. (I don't know much about FreeBSD Xen compatibility) [13:06] randal: yeah, but you'd do a linuux install, then a xen install, then rnu a freebsd vm. [13:07] (I guess so https://wiki.freebsd.org/FreeBSD/Xen) [13:07] tbh i don't relaly think for most people xen is any better than kvm. [13:07] * brycec dislikes Xen [13:07] Much happier with KVM and the ilk, they don't require any guest customisations [13:07] it wsa better on older hardware as it had paravirtal vm's. but modern cpus have really accelerated extensions for normal vm's. [13:07] and now it's faster to have non paravirtualised. [13:07] If I can't run MSDOS as a virtual machine, what use is it? :P [13:08] vmware took out it's paravirtal functionality. [13:08] i think in esxi 5 [13:08] xen now has paravirtual, hvm, and a hybrid. [13:08] hvm is full virtualisation like kvm. [13:09] the only real advantage i find with xen is it makes it easy for me to host kernels outside the virtual environment and boot specific kernels. [13:09] oh wow that was not worth it [13:09] twss [13:09] Okay! twss! 'oh wow that was not worth it' [13:09] there's also better support for video/pci device passthrough. [13:10] i actually went win 2k8 with hyperv 2012 and it makes xen super user friendly [13:10] but kvm is working to improve their stuuff, and it's mostly because xen forked qemu. but they're going back to non forked. [13:10] so if you want to do video passthrough on xen, at least before, it worked better to use the "legacy" qemu option. [13:11] video passthrough on this lenovo in xen was fun [13:11] by better i mean "it worked" rather than "it failed". [13:11] The way I see it, at least in my workloads, there are two types of useful virtualisation: full machine a la KVM, or containerised a la OpenVZ. Everything else outside that scope is just more complicated than it's worth. [13:11] heh [13:11] brycec: i actually like xen [13:12] windows hyperv is fast, but i am seriously disliking it [13:13] freebsd guests are still faster in xen tho [13:13] grody: were you doing paravirtual or full virtual for xen in freebsd? [13:13] even more so when you PV fbsd [13:13] i've tried freebsd with xen and vmware [13:13] xen has this annoying problem with mtu's above 1.5k [13:13] firstly hvm then pv [13:13] grody: you should hvm. [13:13] it actually works better. [13:14] the pvhvm thing should be better still [13:14] not hit that yet, doung pfsense with tagged vlans in xen and it seems fine [13:14] but yeah, there's a hvm kernel config. [13:14] grody: this was real larger mtu's [13:14] maybe vlan doesn't add enough [13:14] ah [13:14] there's a hard coded limit in some driver. [13:15] it's fixable [13:15] yea im still legacy 10/100 here [13:15] i still couldn't do over 2k [13:15] but slightly larger worked. [13:15] it always erks me when i seem to hit lots of "weird" problems, and other people don't. [13:16] haha and you google high and low only to find your question asked but never answered [13:16] grody: that's what i say haha [13:16] grody: and then ytou find out it's been happening for years. [13:16] i remember when i heard about the windows uptime bug [13:17] it crashed after 48 days of uptime or something with a wrap around. [13:17] i'd never hit that buug :/ [13:17] (i did use that dirty windows for a bit) [13:17] xen 4.1 says my mobo doesnt do iommu, but 4.5 is ok with it, couldnt find that one anywhere [13:18] i went evil buying a new tablet [13:19] i got the linx8 win8.1 .. now running arch [13:19] grody: it's probably because new motherboard and old scipset. [13:20] also 5520 is blackedlisted. [13:20] getting a vkeyboard up was fun, had to ssh most of it [13:20] err blacklisted. [13:20] and so vt-d is strictly possible, but things disable it [13:20] not that you're using that chipset [13:20] mercutio, no idea it is a pain of a lappy [13:20] lenovo s205 [13:21] uefi is skiwiff too [13:21] i was doing vt-d on z77 for my gpu pass through [13:21] not all motherboards supported it. [13:22] oh amd [13:22] you like amd don't you grody :) [13:22] wel for a fraction of pruce to get eq. [13:22] its the pepsi of cpus [13:23] i have ex-lease laptop, it was old when i got it [13:23] and a chromebook [13:23] i am thinking of sticking that special boot thing on it [13:23] linuxbios? [13:23] err coreboot it seems now [13:24] it has the google one, but if it runs low on battery then it reverts to only booting chromeos. [13:24] and it's booting in legacy mode and you have to press ctrl-l as you boot [13:25] i kind of wish coreboot was used more by now. i kind of hoped it'd take off. it is interesting that google are using it though [13:25] uefi isn't really that wonderful. [13:25] That's what she said!! [13:25] and it's huge and complicated. [13:26] really the boot loader should just be doing the init system, then providing resources to the initial os. [13:26] err hardware init [13:26] i'm ok with things like a little gui to overclock, and update bios from the gui etc. [13:26] but in the normal course of boot it should juust do the minimum, and not have a hugely massive api [13:28] http://www.uefi.org/sites/default/files/resources/2_4_Errata_B.pdf [13:33] *** grody has quit IRC (Ping timeout: 240 seconds) [13:36] *** grody has joined #arpnetworks [13:36] that was fun [13:42] what was? [15:14] This turned out to be pretty entertaining http://www.therestartpage.com/ [15:14] (click things, move windows, fiddlw with stuff. It's interactive.) [15:36] heh... that's cute [15:36] I'm booting openstep [15:36] Steve's Soul powers these machines. :) [15:49] ok i hate windows hyperv [15:49] im going back to debian xen [15:50] it lags like hell running freebsd guests [15:50] linux is fast as hell mind [15:59] network lag? [16:12] *** dne has joined #arpnetworks [16:55] *** kevr has quit IRC (Excess Flood) [16:57] *** kevr has joined #arpnetworks [23:38] is anyone else seeing ping spikes to 4.2.2.2 but fine to 4.2.2.1. i assume 4.2.2.2 is probably getting ddos'ed or something, it's just curious and my usual "test ip" [23:44] I don't monitor it... But I'm not surprised [23:44] 4.2.2.2 is the ip "everybody" knows and hits [23:44] 4.2.2.1 is far less-known [23:44] mercutio: 4.2.2.2 has always had terrible ping latencies for me [23:45] http://kremvax.acfsys.net/smokeping.cgi?target=Remote.l3dns [23:45] acf: it's been mostly fine for me before [23:45] i don't monitor to it i just check internet stuff with it at the time [23:45] wow it's really bad for you since like the end of june [23:45] but before that it was fine [23:46] is that on a vm? [23:47] no, that's ARP Metal [23:47] interesting [23:47] yea, it's super strange [23:47] i was just lookig athe localhost ping time [23:47] i suppose it's pretty stable, it jut seems high [23:48] mine sits around 10u on an i3-2100 [23:48] http://paste.unixcube.org/k/479429 [23:48] yeah i'd already tried from arp native [23:48] well vm on arp [23:48] yea, it's not going through anything strange afiact [23:48] but i did manage to test from one location that seemed better [23:49] it was better when it hit san jose 4.2.2.2 rather than los angeles 4.2.2.2 [23:49] ah right, that's anycast [23:49] yeah, but los angeles seems worse than san jose [23:49] like way worse [23:49] maybe I should start monitoring 4.2.2.1 [23:49] i haven't got historic data, and you do :) [23:50] i wondered if it was some new ddos or something [23:50] i had weird slow gtt behave earlier today [23:50] then i saw someone reporting about gtt issues on outages [23:50] is *that* what that was [23:50] oh you noticed weird gtt shit? [23:50] it was pretty chronically bad. [23:50] I didn't have much time to debug at the time [23:51] but something was clearly not right [23:51] i still don't know who gtt is compromised of properly. [23:51] but their network seems a badly managed hodge podge atm [23:52] i think it's gtt, tinet, nlayer, mzima, and someone else [23:52] something like that [23:52] I guess gtt just bought everyone up [23:52] what [23:52] and didn't really try to integrate anything [23:52] try goign to www.gtt.net [23:52] umm [23:52] it's not loading, and saying "checking your browser before accessing gtt.net" [23:52] yea [23:52] and to allow up to 5 seconds [23:53] it's been way more than 5 seconds. [23:53] appears to be some Cloudflare anti-ddos thing [23:53] yeah [23:53] so gtt had massive ddos attacks today i imagine [23:53] i thought gtt were bigger than cloudflare [23:53] it's kind of scary when gtt are doing anti-ddos protection with cloudflare and their main web site doesn't even work [23:54] I think cloudflare are super experts at anti-DDOS though [23:54] what's that web host tracker thingy [23:54] for HTTP anyway [23:55] the one that usedd to say about apache vs iis [23:55] netcraft? [23:55] that's it [23:55] oh www.gtt.net loads now [23:55] it did for me, after > 5 seconds :P [23:56] http://toolbar.netcraft.com/site_report?url=http://www.gtt.net [23:56] so it looks like it was self hosted 5th feb 2015 [23:57] huh yea [23:57] just clicked refresh there [23:57] That's what she said!! [23:57] then the CloudFlare one showed up [23:57] it only recently changed from windows to linux too [23:59] https://www.staminus.net/gtt-stops-offering-flowspec-what-this-means-to-ddos/ [23:59] cloudflare use ntt [23:59] at least what i've noticed for communication to origin web sites
