Hi all,

[UPDATE]

Just updated some new packages to the pvetest repository (bugfixes and some new features):

  • Fixed drive order bug (KVM)
  • Allow up to 4094 bridges
  • update to the latest vzctl
  • Use option –sparse for qmigrate
__
We just uploaded new 2.6.24 and 2.6.32 kernels to our pvetest repository.
(deb http://download.proxmox.com/debian lenny pvetest).

Both kernel branches are using qemu-kvm 0.12.3 and gPXE 1.0. Network boot should work now without issues, tested also with Microsoft WDS from Win2008 r2.

Both kernels are tested in our lab and I encourage everybody to test also.

Change log 2.6.24 (KVM and OpenVZ):

  • update to qemu-kvm-0.12.3
  • include gPXE 1.0 network boot
  • update e1000e to e1000e-1.1.2.tar.gz

Hello Martin,

i have updted one server to the latest 2.6.24 Kernel. We have a time critial VM running under Windows XP. The Software, that runs on this machine needs a usb hardware dongle for the copy protected application. Till the Kernel 2.6.24-10 the machine runs stable with no problems. Now i have installed the latest 2.6.24-11 Kernel and the latest tools.

Now, the machine has problem to find the usb hardware dongle. To attache the hardware dongle to the xp machine, we use anywhereusb and Belkin Network USB Hub that works great till the latest pvetest.

How can i help to "debug" the problem?!

Regards, Valshare

Code: 
pve-manager: 1.5-8 (pve-manager/1.5/4674)
running kernel: 2.6.24-11-pve
proxmox-ve-2.6.24: 1.5-22
pve-kernel-2.6.24-11-pve: 2.6.24-22
pve-kernel-2.6.24-7-pve: 2.6.24-11
qemu-server: 1.1-12
pve-firmware: 1.0-4
libpve-storage-perl: 1.0-10
vncterm: 0.9-2
vzctl: 3.0.23-1pve8
vzdump: 1.2-5
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.12.3-1

so, now i have done a downgrade to kernel 2.6.24-10 and all works fine again.

Code: 
pve-manager: 1.5-8 (pve-manager/1.5/4674)
running kernel: 2.6.24-10-pve
proxmox-ve-2.6.24: 1.5-21
pve-kernel-2.6.24-7-pve: 2.6.24-11
pve-kernel-2.6.24-10-pve: 2.6.24-21
qemu-server: 1.1-12
pve-firmware: 1.0-4
libpve-storage-perl: 1.0-10
vncterm: 0.9-2
vzctl: 3.0.23-1pve8
vzdump: 1.2-5
vzprocps: 2.0.11-1dso2

Aparently there is a bug that noone on the kvm dev team is working on for drives over 1TB and virtio. Just an fyi on that. Also, does the new kernel have nfs support built in? I installed nfs-kernel-server but I get failures.

All our kernels support nfs - its a bug in the init.d script which prevents starting the server on 2.6.32 (but nfs on 2.6.32 is known to have other bugs). So I would simple use nfs-user-server

I actually updated to their parched nfs-kernel-server-6lenny2 and it works now.

Seems that this upgrade (2.6.32-2 and kvm 0.12.3) help ALOT on my high CPU load on the host when guest is doing alot of IO. :)
So, keep up the good work :)

Hi, no one has the same problem with Network to USB Hub? Can anyone test it please?!
Martin, can you verify the problem?
 
How have the KVM 0.12.3 packages been compiled?
I ask because, i manually compiled 0.12.3 before, and when compiled against the version of glibc and kernel headers shipping with proxmox i had serious problems with network stability (under heavy load such as multiple instances of bittorrent the network would go down in the guest, requiring me to ifconfig it up/down), however having recompiled kvm using a glibc compiled against 2.6.32 kernel headers the issues have gone away.
 
If you are using virtio, that is a known bug and you should still see the problem under newer kernels with heavy load, if you are not, lucky you :D
 
During offline migration i have this error:

Maybe some ideas to fix it: http://www.finalcog.com/rsync-vm-sparse-inplace-kvm-vmware

OK.

--edit
Should it improve performance of migrating raw volumes? 30gb raw, empty disk:

At first i waited long for rsync status for raw disk, maybe there's a problem. Stale copy maybe should be created via remote command or is it piped through SSH?

not ignored, but it looks that there is not quick solution. can you give me (again) complete instructions how to reproduce the issue?

Hi Tom,

thanx for reply.

We use a this and this Network USB Hub for a time critical Application that use a USB dongle for copy protection. Both Hubs runs without any problem.

After upgrade the Proxmox Testserver from

The Network to USB Hub don´t work anymore. The Connection to the Network USB Hub lost every one(?) minute and the application exists. After downgrade the testserver to the "old" kernel / proxmox tool all runs fine again.

Think there is a bug in qemu-server (?). How can i help to debug the problem!?

Regards,

Valle

we have no such hardware/software/dongle here and therefore we cannot test and reproduce this. so if you want that we try to reproduce the issue here we need all components.
 
Re: New Proxmox VE Kernels 2.6.24 and 2.6.32, including KVM 0.12.3 and gPXE network b

i can send you a bridge for testing, if you want?! Or if you want, i can give you access to the Server / Client.

So its a network problem? If so, what network card emulation do you use? Try another one. Also test with other kernels. Does tcpdump give some information?
