Re: [Xen-users] Can Xen run 32, 32PAE and 64-bit fully virtualized domains run side-by-side?

["Omer Khalid" <Omer.Khalid@xxxxxxx>]

Hello Krysan,

I am trying to run 32 bit PAE Para-virtualized VM on a x86_64 with Xen 3.0.3 64 bit. I always get this error: Xen Image is not compatiable.

You said in one of your messages on the Xen user list that you are running 32 bit, 32 bit PAE and 64 bit para-virtualized and HVM VM's with out any problems, where as in some threads from Jan 2007, it was argued that its not possible! I  am confused!

Which version of Xen are you using? And are there specific configuration one have to make for domU images?

Any help would be much appreciated! Best Regards

Omer

Yes, on an x86_64 host you can run a mix of 32-bit, 32-bit PAE, and
64-bit fully virtualized domains side-by-side.  I have also run 64-bit
paravirtualized domains side-by-side with fully virtualized domains.

Weekly I boot up the following domains simultaneously on x86_64 host:

SMP 64-bit SLES10 paravirtualized domain
SMP 32-bit SLES10 fully virtualized domain
SMP 32-bit PAE SLES10 fully virtualized domain
SMP 64-bit SLES10 fully virtualized domain
UP Windows XP fully virtualized domain
UP Windows 2003 Server fully virtualized domain

Once the domains have booted, I log in and run top command in the SLES10
guests and Windows task manager in the Windows guests.

Hi,

Can Xen run 32, 32PAE and 64-bit fully virtualized domains run
side-by-side?
Or all DomainUF has to be the same mode?

Thanks,

Liang
