Maybe some more details: What i need is just to use a gui to manage kvm machines, no openvz. I also don't need fair scheduler, as setting cpu affinity and maybe renice is enough for my needs. With the proxmox kernel i have a lot of problems of guest hangs, not only with virtio, but also on...

Assuming i need to use only kvm and not openvz, and i'm not interested in fair scheduler patches from proxmox, can proxmox work without problems on a very recent vanilla kernel (>= 2.6.30) with more updated kvm without too many issue? anyone have tryed to do it?

Bad news. Even with IDE block device, my machine have just freezed...

Ok, another update. Also the second guest suffer the issue, it is just freezed.

UPDATE: this morning ( i'm in italy timezone ) i found the guest with very high load, caused probably by a lost of connectivity on the primary ethernet interface. On this guest there are 2 eth interfaces, both virtio, one bridget on vmbr0 with the public ip, and the second bridged with vmbr1 on...

Hello. Im investigating an issue where apparently in a semi-random timing, when a guest have some load ( > 0.50 ) sometimes it gives some kernels messages and it hangs, no way to do anything in the guest. On the host side, i can see the kvm process using 100% cpu, this apart, all the rest is...

At least with debian guest 32 bit ( with both custom from vanilla and debian standard kernels ) it has problems used with virtio. See: http://www.proxmox.com/forum/showthread.php?t=1797

After few days of tests, with disks images on raw files (DON'T USE QCOW!), the best way is to use virtio for both network and disks.

Thanks Tom, this is maybe the better answer i can hope for my questions, and i can understand and agree with your choice to concentrate on the core and other things before to open a public svn and so on. Now i will try to get confident with the code (it isn't so complex nor so many lines...

So, depend on where it block booting: If it block early after the bootloader, it can be a grub ( are you using grub?) configuration issue, if it block after mounting and starting initrd, it is an issue where probably you lack md devices in the initrd image.

Re: Stability of kvm guests - PROBLEM FINDED Ok, my last try was to use: - HOST kernel: standard 2.6.24-7 pve-kernel package - HOST distro: standard debian lenny with pve packages - GUEST kernel: 2.6.26 and 2.6.30 both from debian packages - GUEST disto: debian sid HDD and ETH both with...

if you are able to paste and/or specify your error, maybe someone can tell more about your problem. Anyway, i bet that is just an initrd problem...

Well, i found proxmox VE to be a good product, young maybe, with many improvements that can be done, but good as idea and vision, and look very promising. Now, we notice in the forum than the next version of proxmox will have some exciting new features than i'm sure many of the pve users are...

Re: Stability of kvm guests - UPDATE Little update: - HOST kernel: default latest proxmox kernel from apt - HOST distro: standard debian lenny with pve packages installed from apt - GUEST distro: standard clean base install of debian lenny, with ext3 fs without nor dmcrypt or lvm, 2...

Yes, it is the latest version available by apt repository (download.proxmox.com). Now i'm doing some tests, first of all i'm trying to upgrade the guest kernel from 2.6.26-2 (standard debian from apt) to 2.6.30 (upgrading guest to sid, debian standard kernel ) to see if more updated virtion...

As i can understand ( i'm new to proxmox ve ) a more advanced storage configurator from the web gui will be available in the next release of proxmox ve. For the moment you can use lvm but you need to do that manually by modify /etc/qemu-server/VMID.conf files.

Hello all. I'm testing proxmox ve for server consolidation. I have a quad-core AMD Opteron @ 2.2 Ghz, with 8 gigs of RAM and 2x1TB sata disks with raid 1 HW, on which there is a clean debian lenny base system installed with packages (kernel comprised) from ftp://download.proxmox.com/debian...
