Re: [Xen-users] Can't boot HVM Linux guests on Debian Squeeze Dom0

Success! I was able to boot my HVM sarge guest after making two changes.
The first repaired a simple mistake - I had partitioned a single disk
image using the installer in qemu with a swap and an everything else
partition. The "Domain not found" error went away as soon as I
replaced the erroneous "hda1" with "hda" in the disk parameter.
Shoot, I missed that, too.
The second is more of a long-standing problem. In order to get the
guest to boot, I need to completely disable networking by commenting
out the vif=[] line. Trying to use networking, even with the defaults,
results in the "xenbr0 not found" error seen earlier in
/var/log/xen/qemu-dm-sarge.
That's one that I still don't quite get, but must have something to do
with broken networking scripts.
Another question I have is this: had anybody had any luck using
tap:aio on Xen4.0/Debian? Simply replacing "file:" with "tap:aio" did
not work. I would love to take advantage of the efficiency of the aio
driver, so any advice with regards to this would be appreciated!
Try "tap2:tapdisk:aio:" -- it should work, in 4.0.1. Failing that, try
"tap:tapdisk:aio".
