VM crashed when usb_add executed

[Solved] VM crashed when usb_add executed

I recently upgraded PVE and updated windows kvm guest drivers (SCSI, NIC and Balloon) to version 0.1.22
Now I found out my VM with usb dongles doesn't start if I add the line hostusb: host:xxxx:yyyy to VM's config.
When I remove this line the VM starts well. But it crashes when I'm trying to add usb device manually from qm-console: usb_add host:xxxx:yyyy.
The command with specified bus.port - usb_add host:1.10 - doesn't work too.
I tested Windows XP SP3 and Windows 2008R2 x64 with recent updates.
No one works.

What may it be?

# pveversion -v
pve-manager: 1.9-26 (pve-manager/1.9/6567)

vzprocps: 2.0.11-2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.15.0-2
ksm-control-daemon: 1.0-6


P.S.
I checked VM with old 0.1.15 guest drivers. It crashes now too.
Looks like it depends with last PVE update

Help, please.

The correct syntax in PVE 1.9 is:

hostusb: xxxx:yyyy

(see 'man qm')

Sorry, it's my mistake in the post.
I can paste whole VM's config if you'd like.

 

[dietmar]

Now I found out my VM with usb dongles doesn't star.

So what error message do you get exactly?

# qm start <VMID>

How can I get detailed log?

Dietmar, have you seen this topic?
Is this patch already applied to PVE's kvm?
What version of kvm used in PVE?

 

[cirroz]

Last 88th version has old buffer's length - 1024 bytes.
If I will patch and compile vanilla kvm sources can I replace proxmox's kvm module without troubles?

 

[dietmar]

The usb support is completely reworked in PVE 2.0 - I suggest to test with PVE2.0RC1

 

[cirroz]

I found the cause of problem.

Only one USB dongle ROCKEY4NET works fine.
As soon I add the second ROCKEY4NET key the VM crashes.

But VM crashes with only one Aladdin USB Master Key.

I tried to boot with PVE 2.0RC1 but my computer can't boot from this iso.
I'm going to try again tomorrow with usb-drive.

Fix lies here.
