[Xen-users] How much is involved in porting a new OS to Xen full virtual
I'm looking at SCO OpenServer 5.0.6, for various reasons. I contacted
Citrix, and they weren't interested in pursuing it as a new
virtualization platform, so I'm stuck with VMware. But I'm finding
VMware to be less snappy than I remember Xen being for other operating
systems (and I've tried RHEL on both systems), and to have less graceful
overall system tools for the server.
So, I'm thinking: what's involved in getting Xen to support a new OS for
full virtualization? I've got a Dell server running RHEL 5.1 with plenty
of disk and RAM, Intel chips with full virtualization turned on, it
boots up from the installation CD and then hangs. This happens with
RHEL's provided Xen software, the Xen 3.2 downloads, the commercial Xen
server from Citrix, etc. So, what is involved in the debugging process
for new guest OS's? Is there any estimate of how painful it would be to do?
SCO Openserver is running fine under VMware Workstation, telling it to
use IDE disks instead of the driver complexity to use SCSI. So I assume
that in theory, Xen could support a similar configuration, and get me
away from the VMware bugs of refusing to admit that the image is being
installed on another partition and the available space is from *THAT*
partition, not my / partition. And the VMware init scripts don't handle
auto-starting your multiple virtual images well except from a VNC, which
I consider to be iinsane.
