Re: [Q] How many KVM VMs can run on a single server with regards to RAM and CPU cores If you assign 1 core, then that VM will only ever use one core. All the other VMs can also access the same core. It's not like RAM where the core is dedicated. As for the title question, that is entirely...

0.1-59 here. Are your windows VMs running win2k3? I would expect that to be slower.

I just ran iperf, and I'm getting 3.12Gb/sec between a windows 2012 VM and the host. My server is nothing special. What virtio drivers are you running - maybe that is the difference?

I'm in the same boat. It's really a KVM windows virtio driver issue. I've been running a older driver because it is stable, but there are newer ones out there.

Put a linux VM on your host, then check the speed to the host from there. The windows virtio drivers are not as efficient as linux, and there could be a limiting factor based on your cpu as well.

Re: FreeNAS 64bit hangs on boot I have freebsd 9 x64 running with no tweaks, so I'm not sure what the limiting item is. I suppose that everyone is aware that freenas themselves recommend against running it as a VM? It's designed to be bare metal. The freenas forums are filled with tales of...

I did some more reading on this. In theory it could be done this way: For a qcow2 image on non-lvm: lzo -x backupname vma extract filename targetdir modprobe nbd max_part=63 qemu-nbd -c /dev/nbd0 image.img mount /dev/nbd0p1 /mnt/image Work with the mounted image on host, copy your files...

As far as I know, the best thing to do would be to create a new vmid, and run the restore from the command line to restore into that. Then copy your files out.

GerShock, That's what I was getting at. The process is stuck in the kernel and cannot be killed. I had to wait several days until I could reboot the host, and during that time proxmox backups would not work. It's the same problem that people face with NFS backup locations. I spent way too...

Marco's idea is the right one. I did something like you did for a while. After having to reboot the host a few times, I gave up and started doing local backups and copying them off.

I realize this is an ancient thread, but does anyone have storebackup working with proxmox 3.1, and if so, how?

RAM is cheap and ZFS likes more. I guess what is left is kernel hacking then?

ZFS is probably starved for RAM. I wouldn't bother trying to run it without 8GB of ECC allocated just to ZFS. (The recommended amount is probably 4GB) Unless you want to put together your own kernel, that's the easiest thing to try. I know you don't want to hear it, but if you want to run a...

I'm running a windows server 2012 vm, 8GB Ram assigned, 8 cores, 1 socket. Process hacker states that interrupts are using .23 % of cpu. The kvm itself is using 5.7% cpu on the host. I have sql server running but its not under load at all. What happens if you run just one core?

I'm not sure it will make a difference, but I would not use the latest virtio drivers. I'm using virtio-win-0.1-59.

Is this VM running SQL server by any chance? Does performance improve if you cut back to one socket?

The answer to that is no. Proxmox is not a router. It provides a management interface on a ip you set up during installation, and its up to you to take it from there. If you install suse on a vm, then you configure the ip on that vm just like it was a physical machine. Google "load...

Thanks, that worked! Yes, my terminology is incorrect. I was referring to the individual qcow disks that are assigned to the KVM VM.

I have a VM that runs on containers on a few separate disks. The backup correctly gathers them up into one file, but the restore process dumps them all into the first drive. Since the location data is stored in the vm config file, is there some way for the restore process to put the containers...
