Hi, are there any experiences in using libguestfs under proxmox 1.6 ? I am interested to use such nice commands like virt-resize with proxmox. I am not sure, does libguestfs require libvirt and all this awful stuff ? I dont like that on my proxmox machines.

Well, of course virtio works if the drivers are installed. But Peter told us that he has just converted a physical windows machine to kvm. And if you do this you have no virtio drivers installed ...

Hi, your screenshots show that you are using a virtio disk, not an ide disk. That cannot work. Reconfigure the vm for ide in proxmox and try again

I also have some solid 32 bit vms. Maybe the Problem is that the guest making problems has a 64 Bit Windows 2008 OS ? BTW: What kernel and Versions are you using ? We use:san02:/boot# pveversion -v pve-manager: 1.5-10 (pve-manager/1.5/4822) running kernel: 2.6.32-2-pve proxmox-ve-2.6.32...

This is a clean install. BTW: That Windows vm uses a raw image, no qcow2 or such things

Hi, we run a Windows 2008 R1 x64 vm on proxmox 1.5. That Windows machine is freezing about once a day which means that you cannot enter anything on the console or ping or rdp to that vm. Proxmox then shows a vm cpu usage of 104 % We tried everything, virtio and ide, different nics...

We have really good success in limiting io on proxmox in the standard configuration. For example: ionice -c3 backupscript.sh allows backups only in idle-times which means backups have no impact on running processes. ionice -c2 -n0 -p pidofkvmprocess allow some better io quality for specified...

Does anybody know a trick of how i can force a correct drive order using proxmox ? Or any hint in which file is the source code to build the argument line so that I might be able to resort them by myself ?

Yes, you can perfectly do that with proxmox. We are doing the same. Regarding GUI, yes, I think you can define this network infrastructure using the GUI. We dont use the GUI for interface configuration since every interface change through the GUI requires a proxmox reboot which is a no go for...

I can also confirm the problem with reordered disks an qemu-server: 1.1-12 After adding a virtio1 disk the virtio1 disk becomes vda while the virtio0 disk becomes vdb even more worse: I have no idea of how to fix it, i cannot reconfigure all vms ... The command line seems to be correct but qemu...

Hi, I have just installed kvm-0.12 from the proxmox pvetest repository. kvm should now be able to do a live migration including block level migration, see http://www.linux-kvm.com/content/qemu-kvm-012-adds-block-migration-feature How can i do a block migration now in proxmox ? Does somebody...

I finally got it working, the /etc/network/interfaces file has to look someting like this: auto bond0 iface bond0 inet manual slaves eth4 eth5 bond_miimon 100 bond_mode 802.3ad auto vmbr1 iface vmbr1 inet manual bridge_ports bond0.112 bridge_stp off...

Hmm, sounds good. I don't have a free nic but I have a bonding device for the storage network where I might be able to add vlans. Unfortunately it seems not possible to add vlans to bonding devices. I tried this: auto bond0.111 iface bond0.111 inet static address 10.65.1.12...

Hi, I have a cluster of 3 proxmox servers which hosts virtual Linux machines. 3 Linux vms need to be interconnected via an additional virtual nic in a private 10.x.x.x network. As long as I host the 3 vms on the same proxmox node this is no problem, I define a "blind bridge" without any...

We also sometimes observe this problem. Yes, Stop and Start helps, another Method is to just wait for about 40 Minutes. I always thought the Windows is doing something "magic" like a filesystem check in these Situations.

Yes, I have verified it with a windows vm and iometer. Raw instead of qcow was a big performance boost and nocache significantly boosted the result again. Unfortunately I did not document the results and I don't remember the exact numbers.

See: http://www.linux-kvm.org/page/Tuning_KVM If you're using raw volumes or partitions, it is best to avoid the cache completely, which reduces data copies and bus traffic:

Hi, my experience is: 1) use raw disks for winmdows speed, not qcow2 2) use cache=none by manual editing the /etc/qemuserver/vmid.conf file like this: virtio0: vms02:125/vm-125-disk-1.raw,cache=none Afterwards performance is ok even with IDE 3) if you want to double that performance again, then...
