Hi folks,

I do have a problem with usb pass through to a KVM machine, and dont know how to resolve it:
First i want to say i do use proxmox 1.9 with the latest updates and i have an Ubuntu 10.04.3 LTS minimal kvm guest also with the latest updates.
On the guest there is a database and some software protected by a usb-dongle (to protect the database connection to other workstations in the network)
I did add the usb-dongle via
Code: 
qm set 104 -hostusb 064f:03e9
to the host and everything was fine for a couple of weeks until now.

But i had to do a reboot of the server because of a change in the /etc/vz/vz.conf file and now i am unable to passthrough the usb-dongle :(

At first the virtual machine did not start at all, and after removing the usb-dongle i could start up the machine.
When i try to replug the usb-dongle in the host, the virtual machine is crashing immediately!

i played around with the /etc/qemu-server/104.conf file (commented out the usbhost, enabled it again), but whatever i do, without usb there is no problem, as soon i plug in the dongle, the machine do not start up or crashes if it was running before.
In the syslog of the host and the guest i did not find anything about this problem.

I dont know what to do, but this virtual machine is very important, because this database is hosting all accounting information of the company i work for (bills, stock, etc)

Please anybody help me with this problem
 
to make the picture more complete, here is the dmesg output on the host for this usb-dongle:

Just tried to passthrough another USB device (a usb cd-rom) to the guest and i have the same issue. (with passthrough it hangs, without it boots perfectly)
So it looks like to me, there is an regression in the last updates regarding the usb-passthrough. Is this possible? Whats the best thing to do, to get it up running asap?
Install a new system on a physical machine and migrate the database?

Here is the version output from pveversion:

proxmox:~# pveversion -v

downgrade the updated packages, e.g. use pve-qemu-kvm 0.15.0-1

http://download.proxmox.com/debian/dists/lenny/pve/binary-amd64/pve-qemu-kvm_0.15.0-1_amd64.deb
 
[SOLVED] hostusb problem

Indeed, downgrade the pve-qemu-kvm to version 0.15.0-1 did the trick.
Now it works again like expected - thanks a lot tom.

Should I file a bug somewhere?

Thanks again and greetings from Vienna :)
 
Re: [SOLVED] hostusb problem

Same problem here with Win2008-Server guest in KVM. Downgrade from pve-qemu-kvm 0.15.0-2 to pve-qemu-kvm 0.15.0-1 solved the problem too.
Thanks!
 
Re: [SOLVED] hostusb problem
