Great guys!

One question though, how can we specify 'vhost=on' (i.e. VhostNet) for our virtual machines?

Edit: Answering my own question: module 'vhost_net' must be loaded :-)

Hi,

I have some trouble with a Windows 2003 Guest 32Bits, when i stress io (disk / and networks, with a big transfer by FTP SSL) the TSE connections hangs for 15 - 30 s....

pveversion -v
pve-manager: 1.7-10 (pve-manager/1.7/5323)
running kernel: 2.6.32-4-pve
proxmox-ve-2.6.32: 1.7-28
pve-kernel-2.6.32-3-pve: 2.6.32-18
pve-kernel-2.6.32-4-pve: 2.6.32-28
qemu-server: 1.1-25
pve-firmware: 1.0-9
libpve-storage-perl: 1.0-16
vncterm: 0.9-2
vzctl: 3.0.24-1pve4
vzdump: 1.2-9
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1dso1
pve-qemu-kvm: 0.13.0-2
ksm-control-daemon: 1.0-4


On this host i have an debian guest (big ftp server), it's running very well...

I tried 2.6.35 kernel same result.

On my Windows Guest i installed the lastest virtio drivers from kvm (virtio-win-1.1.11-0.iso).

These VM is a copy of my production, running very well in 2.6.32 Kernel / 1.6 From September 2010.

The only big change i made on this test server at installation : no LVM, i'm using EXT4...

I'm planning to move to kvm 0.13 cause of some random "CPU Stuck For 4096s" bug but now i'm not really sure...

thanks

Nsc
 
post the setting of your guest (see /etc/qemu-server/VMID.conf)
 
Windows 2003 :

name: VM-XXXXX-FTP
ide2: iso:iso/virtio-win-1.1.11-0.iso,media=cdrom
bootdisk: virtio0
ostype: w2k3
memory: 2048
sockets: 2
vlan2: virtio=7E:E8:89:75:DD:5A
boot: cad
freeze: 0
cpuunits: 1000
acpi: 1
kvm: 1
onboot: 0
description:
cores: 1
virtio1: local:101/vm-101-disk-1.raw
virtio0: md2:101/vm-101-disk-1.raw

i tried with
virtio1: local:101/vm-101-disk-1.raw,cache=none
virtio0: md2:101/vm-101-disk-1.raw,cache=none

no change...

i'm not sure but it's looks like a "extends problem".

i format my etx4 partition, 1.8TB > 5min (not a full allocation then).
i create my disk of 32Gb in proxmox : instant
i format my disk in Win2003 : something like 2 min (not a full format)

then after all, i ftp / freeze / removed files, ftp / freeze / remove files, ftp etc...

now it's look a bit more stable, i'm waiting for the hang.

Is this possible ?
 
your settings for the vm looks ok, but we never test with ext4 so I can nothing regarding ext4. also using softraid is not recommended, never tested and not supported (md2 looks like md raid?)
 
on my production server, i have soft raid too.

pveversion -v
pve-manager: 1.6-5 (pve-manager/1.6/5261)
running kernel: 2.6.32-3-pve
proxmox-ve-2.6.32: 1.6-25
pve-kernel-2.6.32-3-pve: 2.6.32-18
pve-kernel-2.6.32-4-pve: 2.6.32-25
pve-kernel-2.6.24-11-pve: 2.6.24-23
qemu-server: 1.1-22
pve-firmware: 1.0-9
libpve-storage-perl: 1.0-14
vncterm: 0.9-2
vzctl: 3.0.24-1pve4
vzdump: 1.2-8
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1dso1
pve-qemu-kvm: 0.12.5-2
ksm-control-daemon: 1.0-4

only "big" difference, i have lvm for sata ...

i will try to stress the production guest tonight without any user on it, we'll see.
 
Hi nsc,
i'm currently testing win2003 vm, and for the moment i don't have any problem. (virtio disk through iscsi lun with cache=none and virtio nic)

do you known if your problem come from the disk or from the network ?

if it's come from the network, maybe you can try this .reg , it disable tcp offload.
(i think current virtio win nic driver doesnt support vhost for the moment)

Code: 
Windows Registry Editor Version 5.00 
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters]
"DisableTaskOffload"=dword:00000001

i've posted 1.1.16 virtio drivers here:

http://rapidshare.com/files/434210514/virtio-win-1.1.16.iso

maybe it can help you.

Best Regards,

SPiRiT
 
thanks Spirit i'll try this.

i dont know if it's coming from Network or Disk. Only things, i can reproduce it easily with this "method" : Filezilla client, FTP SSL connection, massive download from 100Mbps serveur => RDP connection lost after 5 - 10min, TSE Session "Reset".
On the host i see nothing from atop / htop command, no swap, no io stuck etc...
And my second guest (Debian) is running well.

I think it's a pure windows problem... like i have a "pure" debian problem on my other host :(
 
hi guys,

I have the same problem with a Windows 2003 Domain Controller. Just RDP disconnects, no other viewable errors. Is there a problem with vhost on windows guests?
I use the 2.6.35 kernel on proxmox.
 
ok still having the problem.

I just have to start downloading and double click to My Computer, my TSE session reset and dies....
 
yes i tried the .reg.

now i'm trying with realtek network card for my guest, removed the virtio...
 
Is kernel 2.6.35 still available (as it is now in 1.6)?
 
spirit said:
try the .reg, i was having same kind of problem with xenserver last year.

(i'm not sure than virtio win drivers can use vhost=on offload for the moment)
Click to expand...

...worked for me now. I also updated to the new 2.6.35 kernel from pvetest. And also I´m testing this patch which boosts my desktop http://tinyurl.com/336bm3d.
I don´t see any performance jumps right now. Is KVM using cgroups by default ?
