[Xen-users] Problem with installing/running domU OS on HVM machine

Hi,

I have problem installing or running domU OS (Windows XP or Redhat 7.3).
The machine runs CentOS 4.4 X86_64, Xen-3.0.3. Paravirtual domU works
without problem.

The problem is that when I run command "xm create <config>",
nothing
would happen. hvmloader does not seem get started at all. I''ve tried
installing both 64bit and 32bit vnc, sdl but did not see any difference.

Anything special about installing domU over X86_64 dom0?

Simon

Did you check if you have an hvm capable machine?

As long as you don''t see "VMX ON" in xm dmesg, it is not
correctly
working, that can mean, it isn''t enabled in your BIOS options, opr not
supported by CPU or BIOS.

Re: [Xen-users] Problem with installing/running domU OS on HVM machine

The machine has Athlon 64 dual core CPU and uses AM2 socket. HVM is
supported based on "xm dmesg":

Based on postings I''ve read so far, hvmloader must be compiled for
32bit. However, it does not work if I copied the file from a 32bit
CentOS machine and use on the Athlon 64 machine.

I am not sure if that helps, but it sounds a bit "shaky" to copy only
a single file - it might not match with the whole rest.

Maybe you should try to use the whole package you built on the 32bit machine.

Re: [Xen-users] Problem with installing/running domU OS on HVM machine

I read some postings on this list saying that installing and running
32bit domU should work under 64bit dom0. Does it mean only for
paravirtualization? not for vmx?

I can try using 32bit for both dom0 and domU for the machine, but I''d
like to run 64bit dom0 and 32bit vmx domU.

Yes, I think you can run 32 bit domU on 64 bit dom0. I made that once,
in fact only with paravirtualization,  but I don''t have a 64bit
machine at hand permamanently.

But I don''t understand what this has to do with my previous posting.
I only said, I think it''s probably not a good idea to copy only a
single file from the 32bit Xen package into the 64bit Xen
installation. Maybe others know more about this.

Are you sure?
For my information, you need to have the same bits on domU and dom0 with
paravirtualization.
Only hardware virtualization can combine different bitwidths...
