Re: [Xen-users] XP64bit in Xen 3.0.3 under OpenSUSE 10.2

Thank you, Mats and Mark, for the answers!
I have copied xmexample.hvm to \etc\xen\vm, changed it and renamed it to 
Then used 
#cd /etc/xen/vm
#xm create myvm.hvm.
It's interesting that XP64 in xen 3.0.3 in Opensuse 10.2 starts with  parameters
Regardless of that fact that XP 64 asks to turn on APIC in firmware, but
not ACPI!
I have started XP64, it started but at last but buzzed on text
screen: "Setup is starting Windows"
I think XP64 is not supported in Xen 3.0.3 :(
And userguide says nothing about it, only that XP is supported in
May be XP64 is supported in xen 3.0.4. But for Opensuse there are no x86_64
xen rpms -- only 686 rpm:(
