[Xen-users] Black screen in vnc conexion to hvm machine (etch without X)

[Javier Barroso <javibarroso@xxxxxxxxx>]

Hi list,

No always happens. I tried to find answers in this list, but my search
was not very useful (I read the threads links related) [1]

I have a etch hvm xen machine in a dom0 etch

Some times I try vnc connect to domU and a black screen appears. I
can't connect by ssh and no service works inside domU.

In my menu.lst I added recently 'root=/dev/hda1 ro apm=off acpi=off
noapic' because I had date/time problems

Do you have any tip about (xm dmesg apparentlyu doesn't says nothing [2])?

Thanks
PD: Please add me to cc: , I'm not in the list.
