SpeedBus has quit IRC (Ping timeout: 240 seconds) up_the_irons: is virtio supported out-of-the-box in freebsd 10?
wondering if i should go all virtio when i make v10 templates ***: acf_ has quit IRC (Ping timeout: 240 seconds) staticsafe: up_the_irons: i believe so, might want to test it out though up_the_irons: k
my smallest host, "mercury", will get an upgrade to Precise (Ubuntu 12.04) this Wednesday night
notice to be sent out soon
(not sure if anyone here is on it) toddf: does that correspond to a kvr# or does it predate kvr# ? staticsafe: which kvr is it? toddf: ;-) jbergstroem: up_the_irons: virtio drivers in vm is still so-so performance wise (not half as bad as 9 though)
at least according to my testing staticsafe: jbergstroem: is it still better than the current VM disk IO drivers? jbergstroem: staticsafe: not really. i kind of trust them more as well
network drivers works great though -: staticsafe nods ***: robonerd- has joined #arpnetworks up_the_irons: toddf: staticsafe : technically, it is kvr01, but it was named before i made the "kvr" prefix naming system :) staticsafe: ah ***: robonerd has quit IRC (Ping timeout: 240 seconds)

robonerd has joined #arpnetworks brycec: up_the_irons: What does "kvr" stand for/mean anyways? ***: acf_ has joined #arpnetworks toddf: brycec: I'm guessing here, 'Kernel Virtual aRpnetworks' up_the_irons: brycec: KVM Virtual Machine
Kvm ViRtual machine
^ ^ ^
:) brycec: lol m0unds: virtio was supported as of 9.2
in freebsd
i haven't had any issues with it, and disk latency and stuff is lower than the default virtual ide driver or whatever it uses without virtio mercutio: i imagine that other tenants using virtual io will improve performance too
will improve node performance in general staticsafe: yeah mercutio: it's really hard to benchmark such things though
i'd like to see the vnc speed up :/ staticsafe: VNC is slow everywhere mercutio: that's the main thing i actually find slow
heh m0unds: it's slow on my KVM host at home on my local network
via my local network
it's just universally slow as balls mercutio: if it could just echo characters in a more timely fashion it'd be a nice start :)
damn
so the update may nnt help m0unds: yea - i only run a pair of vms on my box, and the load is less than 2.00 on a dual quad core box mercutio: do you find keys echo slow? m0unds: yep mercutio: as well as full screen refreshes
full screen refreshes i can understand slihgtly more m0unds: yeah
i found that using screen sharing or whatever the quasi-vnc client in osx is is pretty bearable mercutio: but it's laggy enough to not have good feedback loop from here at least m0unds: yeah. i only use vnc if i screw something up though mercutio: i was running chrome over remote X the other day
it's quite usable m0unds: or if i need to interact with a box at boot mercutio: err on lan
except when resizing
yeah same m0unds ... but when i screw something up i'm easier irritated m0unds: lol mercutio: i screewed up the openbsd upgrade m0unds: yeah, i remember you had a hard time w/that
sounded...fun? mercutio: heh
haha
that's oen word for it m0unds: not the right word, necessarily
lol mercutio: oh well it's only that update that is meant to be a pita
there's a new non vnc consoel thingy too
i think it was called spice?
oh spice is in precise ***: acf_ has quit IRC (Ping timeout: 268 seconds) up_the_irons: yeah spice is in precise, but i never tested it toddf: having a portal knob to twiddle disk type would be awesomeness, just sayin; I might be more inclined to try virtio nic or disk if I knew _I_ could revert in the timing of a shutdown/powerup brycec: Spice is pretty effing smooth. toddf: spice is the rolls royce of vm remote connectivity
consider
1) secure! can do password and even ssl ca keying etc
2) permits `sharing' audio/virtual usb disk/virtual usb cd/virtual usb floppy ..
its awesomeness
if you have a kvm capable system throw the latest proxmox.com on it and play; ignore the web ui notice there is no commercial licence and it works fine ..
in unix 'remote-viewer foo. brycec: Exactly what we do toddf: brycec: do you have a .mailcap and .mime.types recipie? I have failed to create a working one .. brycec: Also fun: the cluster nodes will forward the spice (or vnc, etc) connection amongst each other. (I login to host A, get a spice connection for a VM running on host B, and the connection magically works via host A)
toddf: Nope. Never ever messed with those. toddf: brycec: how do you connect to spice? directly via tcp or via some inetd alike running 'qm spice-server 100' or alike ?
I'm talkin by hitting the 'spice console' button in the web ui brycec: toddf: How does Proxmox do it? Internally, can't quite recall. But I click the SPICE button and it downloads "foo", then I run "remote-viewer foo" toddf: but anyway, semantics. sometime in the next two years I'll be surprised if arpnetworks doesn't have a spice remote viewing option. I'm sure those of us who have played with similar would be glad to work out any logistical and/or cmd line examples for up_the_irons if it would help ;-) brycec: (And foo has certificate and host details_) toddf: yes, indeedy it does mercutio: i've never actually tried spice
but if it works better than vnc i'd be keen to try it ***: grepidemic has quit IRC (Ping timeout: 240 seconds)
grepidemic has joined #arpnetworks toddf: mercutio: better is subjective, i honestly can't tell difference between visual display; its the fact that it is secure to the kvm process that interests me most
extra bells and whistles are nice, but not my personal selling point ;-) ***: SpeedBus has joined #arpnetworks up_the_irons: toddf: portal knob to twiddle disk / nic arch. is something i'd like to work on soon toddf: up_the_irons: awesome ;-) up_the_irons: :) toddf: I've desires to use virtio nic, but os implementation issues can crop up, and ability to revert to intel nic and test at will virtio would be invaluable for me. I've not inundated you with support requests due to lack of desire to do so ..and coordinate testing on my end etc .. ;-)
your 'schedule' cuts out extra work in and of itself (and that is a good thing *grin*) up_the_irons: i think more of your suggestions have become features than of anyone else ;) toddf: lucky me or good suggestions. hopefully the latter. ;-)
though I do, for the most part, have a single os for desktop and server deployment (OpenBSD) I do have a diverse set of experience using and maintaining various VM environments. when I see a good thing not present here yet, I can't help but mention it. I guess you and others agree its a must have at some point ;-)
