Hi All,
I don't know if many of you already tried to run OpenBSD on Xen as a HVM
guest, but here is a small report of my attempts this evening.
The virtual server runs on a debian sarge with xen packages from the
backports debian repository. Hardware is a dell 2950 with cpu
virtualisation enabled in BIOS.
I had to use Paul's boot iso image
(http://www.weirdnet.nl/openbsd/serial/ ) to boot and use the serial
console. I could have used the VNC option but all text was too scrambled
to be really usefull.
At first I attempted to use a physical LVM volume as disk but the
installer failed, I think it was wrong about the disk geometry. I will
take a look at this later.
Second problem: I had to tell xen to emulate a ne2k-pci NIC instead of a
rtl8139 (re(4)) NIC. The re(4) card only gave me lots of watchdog
timeouts and no packets. Even though lots of those were fixed on
current, I still have those errors that's why I am still on ne(4). Due
to a strange bug in xen I have to shutdown the virtual machine and start
it again to have networking work. When I do a reboot I get re(4) again.
If re(4) would work ok this host might actually get very usefull ;-)
As you can see in the dmesg the kernel tells me the clock has a unknown
CMOS layout but don't worry, the clock works ok ;-)
I hope this information is usefull to some of you.
here is my dmesg:
