Hi proxmox team

I have very big troubles with latest version of pve 1.8 and the network of windows guests. The problem seems to be having this bug https://bugzilla.redhat.com/show_bug.cgi?id=630830#c26 . I tested these drivers virtio-win-prewhql-0.1-7-nic.tar.gz and drivers from http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/ . The network works fine only when i downgrade qemu to version 0.13 ( pve-qemu-kvm_0.13.0-3_amd64.deb )

pve-manager: 1.8-15 (pve-manager/1.8/5754)
running kernel: 2.6.35-1-pve
proxmox-ve-2.6.35: 1.8-10
pve-kernel-2.6.35-1-pve: 2.6.35-10
qemu-server: 1.1-30
pve-firmware: 1.0-11
libpve-storage-perl: 1.0-17
vncterm: 0.9-2
vzctl: 3.0.24-1pve4
vzdump: 1.2-11
vzprocps: 2.0.11-2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.14.0-3
ksm-control-daemon: 1.0-5

guest:
Windows 2008 r2 sp1
 
what are "very big troubles"? pls give detailed instructions how to reproduce the issue, I personally have these drivers in several boxes with win2008r2sp1 without troubles so far (but with 2.6.32).
 
Windows is a file server. When traffic pass through it in the order of 10 20 GB, network interface stops. I have to disable and enable network interface to work again. With the old version of qemu machine passes over 500GB.
 
Hello Ashes, Could you confirm you always have the problem with 2.6.35 ?
 
With 2.6.35 yes. With 2.6.32 i have 6 days 100% network uptime under heavy load.

pve-manager: 1.8-15 (pve-manager/1.8/5754)
running kernel: 2.6.32-4-pve
proxmox-ve-2.6.32: 1.8-32
pve-kernel-2.6.32-4-pve: 2.6.32-32
qemu-server: 1.1-30
pve-firmware: 1.0-11
libpve-storage-perl: 1.0-17
vncterm: 0.9-2
vzctl: 3.0.24-1pve4
vzdump: 1.2-11
vzprocps: 2.0.11-2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.14.0-3
ksm-control-daemon: 1.0-5
 
Ok, revert backup to 2.6.32 + qemu 0.14, it's working fine.

2.6.35 + qemu 0.13 working fine too. (this is the solution i used, as i need vm with more than 16 vcpus)

So the problem seem really related to qemu 0.14 + 2.6.35 kernel.

someone here has the same problem (slackware kernel 2.6.35 + qmeu 0.14):

i can reproduce the bug easily, just copy a 2mb file from win2008r2 vm guest to a win2003 share, it's crash immediatly.

maybe we need to wait for fedora15 virtio drivers release (qemu 0.14 + 2.6.38 kernel).

I'll try to test with 2.6.38 ubuntu natty kernel, to see if i can reproduce the bug.
 
Hi Macday how did you install natty kernel?
I have the same problem as you... And want to try natty as a fix (I need KSM)
 
Thank you very much spirit. I´m just downloading. Could you also pn me a detailed "bash-history" for compilation?

Could you also give us a link to virtio driver 1.2.0 ?

Redhat does not allow to redistribute these driver so remove the download and respect their software licenses. You can only use them on Redhat systems with active subscriptions.

Really ?
Well no problem I removed the link from my post.
However I have no control over the dl.free.fr fileserver, so you should remove the link from your post too :)
