Re: [Xen-users] help on FreeBSD using hvm

[Sergi Seira <s.seira@xxxxxxxxx>]

Hello,

CPU time doesn't go up.

I've checked /var/log/xen/qemu-dm.19594.log (I missed this files before
posting):

domid: 3
qemu: the number of cpus is 1
warning: could not open /dev/net/tun: no virtual network emulation
Could not initialize device 'tap'

After searching a little I found that maybe:

modprobe tun

would work, but I get the same error.

Do I have to recompile xen with some tun/tap option?

Thanks for your quick answer.
Regards,
Sergi
