Re: [Xen-users] cant start hvm because of ioemu network device.

[Ori <ori@xxxxxxxxxxxxx>]

I just solved the issue by myself.
Digging in the Qemu logs I've found something like "tap0 unknown interface"
Apparently the tun kernel module was missing, after loading it everything 
works fine.
X logs are quite messy and xm's error messages are not really helpful.

I'm using Xen 3.2.0 on Gentoo as well. kernel 2.6.20-r6
it works nice also I had a lockup once but I think it's related to NFSv4
Right now happily running 4 domUs and some of them are HVM.
Thank you for your interest.
Ori.
