Re: [Xen-users] 64 bit dom0 and 32 bit HVM

[Jason Solan <jsolan@xxxxxxxxxxxxxxxxxxxx>]

I can't say that I've tried moving a PV 32 bit to HVM 32 bit on RHEL 5
64 bit, but i have done it on fedora 7.  I feel pretty comfortable
saying that it should work the same on RHEL 5.

With a 64 bit dom0 I've found that the device_model has to be the lib64
version or it hangs (similar to the issue you're seeing).  Do you have
any fully virtualized domU's on this system?

I suggest trying:

device_model = "/usr/lib64/xen/bin/qemu-dm"
