Same attempt at openSUSE 11.1 Dom0 causes OS reboot .
vcpus =1 works

Can you try to add the following into the Solaris10U6 HVM guest's config
file?
cpuid=[ '1:edx=xxxxxxxxxxxxxx1xxxxxxxxxxxxxxxxx' ]

This forces the PSE36 bit to 1 in guest's CPUID emulation.
I heard some kinds of Solaris guest needs this to load the 64-bit
kernel, or else, the 32-bit kernel would be loaded.

If this works, you can ReplyToAll to xen-devel ML to let more people know.
