1.4 KVM reboot USB problem

[tesquenure]

Hi all,

A USB fax/modem works fine with a linux VM in KVM.
Just if i reboot the VM the USB disappear in the VM.
If i stop (web proxmox) or poweroff (VNC) and start VM all be fine.

is that a known bug?

Regards,

Step 1: Identify USB; You can use the 'hostusb' option:

lsusb

Step 2: To pass through an host usb device use:

qm set <vmid> --hostusb vendor_id : product_id

for example, to pass through the following device to VM 107 (your machine):

qm set 107 --hostusb 0baf:0303

Step 3: You need to start/stop the VM to apply the settings.

PS: for Hylafax be 100% procent that your modem is recognized by fax system. My only success with hylafax was on COM2 modems or PCI...not with USB modems. Please, if you configure this fax server with a USB modem, post the MODEM model (with USB ID) and what was your steps... Thank you!

hi Nick,

I already done all thats steps, and hylafax works fine with this USB U.S. Robotics
fax/modem.
After the 1st start/stop all works fine.
After all start/stop all works fine.
Just if i reboot the VM, USB desappears in the VM.
Then i have to start/stop again.

VM -> KVM SME 7.4 (base on centos)
