That did the trick!! Apparently I was still using the older version of the drivers. :( Upgrading the drivers and switching back to VIRTIO device and everything is working again. Thank u very much Tom!!

WOW - that was fast :-) Will try right away!

Hi @all, I just updated to the latest release 1.7. After a reboot all my Windows VM show me a BSOD. My Windows VM (SBS 2008, Windows 7 x32 and Windows 7 x64) where all running with VIRTIO devices without a problem before. But when I switch the HDD back to IDE the VM will start normaly. Is there...

Hi l.mirzwa, try the latest kernel (kernel-2.6.35-3) on your first server. See also the post from dietmar in this thread. That should improve FSYNCS on your first server. kind regards

Thx Dietmar, here the results after applying the new kernel: pveversion pve-manager: 1.6-4 (pve-manager/1.6/5229) running kernel: 2.6.35-1-pve proxmox-ve-2.6.35: 1.6-3 pve-kernel-2.6.32-4-pve: 2.6.32-21 pve-kernel-2.6.35-1-pve: 2.6.35-3 qemu-server: 1.1-19 pve-firmware: 1.0-9...

Some other numbers after installing the pve-kernel-2.6.32-4-pve pveversion: pve-manager: 1.6-4 (pve-manager/1.6/5229) running kernel: 2.6.32-4-pve proxmox-ve-2.6.32: 1.6-21 pve-kernel-2.6.32-3-pve: 2.6.32-14 pve-kernel-2.6.32-4-pve: 2.6.32-21 pve-kernel-2.6.35-1-pve: 2.6.35-2 qemu-server...

hi dietmar+tom, just testing your latest kernel and noticed that pveperf is showing different numbers: pveperf CPU BOGOMIPS: 42139.81 REGEX/SECOND: 1204265 HD SIZE: 39.37 GB (/dev/mapper/pve-root) BUFFERED READS: 234.62 MB/sec AVERAGE SEEK TIME: 14.22 ms FSYNCS/SECOND...

Thank you very much jcanodk!!! I will check it out right now. kind regards

Hi jcanodk, That is very interesting!. Can you elaborate more please? I looked into installing the server package on my pve-server but it seems that it need to be compiled for the actual kernel right? What package do I need in order to compile it for my pve kernel? (2.6.32-4-pve) Is it possible...

Thx Tom, I am not on OVH. But I did a quick test and rtl8139 ethernet device is working fine. kind regards

Just a feedback: today I started an update the usual way: apt-get update apt-get upgrade I found the following warnings: ... Preparing to replace proxmox-ve-2.6.32 1.6-12 (using .../proxmox-ve-2.6.32_1.6-13_all.deb) ... Unpacking replacement proxmox-ve-2.6.32 ... Processing triggers for...

Thx for your very interessting reply!!! I guess what I am trying to understand is: what is driving the I/O performance in a virtual environement. Is it the OS in the VM or the underlying RAID system for the RAW file. I am running mostly Windows OS in KVM (SBS 2008, Windows 7). So files are...

Hi @All, Just curious: I am running a 1TB RAID 10 system (currently with 64k stripe). I was wondering what the best strip size would be for optimum performance. I use mainly Windows Server VM's with RAW files between 30-200GB. In windows the file format is NTFS with 4K cluster. So basically I...

Sorry - my fault. There was a mismatch between directories and the --dumpdir (typo). After fixing it backup works.

Hi @all, I started a backup today (GUI) and found this error in syslog: Jul 13 13:10:01 cron 4413 (root) CMD (vzdump --quiet --snapshot --compress --storage VM_Backup 202) Jul 13 13:10:02 kernel RPC: Registered udp transport module. Jul 13 13:10:02 kernel RPC: Registered tcp...

Thank you very much Tom!! Looking at it right now.

Thanks to all for your insights. I will see what I can afford...

Hi @all, This is just a question: Currently I am running a PVE Server on an Intel CPU. I am looking into adding a second server and create a cluster. Due too budget limitations I am looking into getting an AMD based system. Would I need to activate Windows VM's every time I move them between...

After spending more time this weekend on this issue here is what I figured out: Since every time I backed up a vm my SBS 2008 showed me a blue screen I decided to reinstall the complete pve server this weekend. I thought maybe I miss configured something. But still SBS kept crashing. Even when...

Hi Dietmar, Here my findings: I used a USB Drive as an alternative storage and backup went fine (tried it a couple of times). So I guess you are right and the problem must be related to NFS. I will check it out ... In any case my SBS 2008 keeps crashing during backup (Bluescreen). I was...
