KVM vm goes to 50% utilization. hangs. needs reset.

Well uptime is a record 19 days. on SMP=1. I'd say that was a bug. I'd like to dedicate more cpu power to a vm than just one cpu

bug: 32bit vm lvm hangs with more than one virtual cpu...


but I do have a similarly configured server with even longer uptime running debian lenny 64bit. that I will be migrating to very soon

we released today a new version with new KVM, you should give it a try.
 
well it's a production box (long story) and I don't want to mess with it until 1.4 is out of beta. And even then I don't know what I'll do, because I hacked a common storage solution /var/lib/vz is mounted on the same physical ocfs2 for both servers in the cluster. That way with a bit of playing with config files, I can bring up a guest on either server in short order.
 
OK this was a year ago. I'd like to know if anything has changed. Recommendations ended up to be single cpu only, no virtio drivers. I'm mostly up to date with my proxmox installations. I'd like the performance that virtio would seem to offer. Is it stable now? Are multiple CPU's ok? Are we more stable than we used to be?
 
yes, a lot improved the last year. I suggest you give it a new try with our new upcoming 2.6.32 with kvm 0.12.5, will be released in a few days to pvetest repository.

so virtio lan is ok ... ?
so virtio disk is ok ... ?
multiple cpu's are ok ... ?


I will probably migrate my mail server over when the kernel and kvm you mention are out of "test"
 
I had the same problem when I deleted an iso image file and booted a machine with that iso in the virtual cdrom. I changed the cdrom to empty/eject and then I was able to boot the system.

I've tried virtio lan/ disk / SCSI and 2X CPU 2X cores. It all seems to work but IDE with raw containers give me the best performance ... as far as I can tell. My benchmarks are pretty unscientific. I haven't tried to gauge virtio lan yet.

Any idea when the above kvm and kernel will be out of 'pvetest' ?
 
the new 2.6.32 kernel (with openvz) has still unresolved issues so we have no release date.

So the 1.6.release has the new virtio code you were talking about? if so, that was quick for not having a release date.
