Issue getting my first Xen domU up

[Eric Bautsch]

Hi Roger.


Thanks for that.

Yes, tap not being there was the issue.....


And yes, the qemu-dm-titania.log would have been the place to look. I feel 
pretty stupid. It says:

qemu-system-i386: -netdev 
type=tap,id=net0,ifname=xnb3.0-emu,script=no,downscript=no: could not open 
/dev/tap: No such file or directory


Got it running now.


Very much appreciated.

Eric
