hanging while install OpenSolaris (Nov 2008 version)

[Peter Teoh]

I got a mid-way hang while installing OpenSolaris on KVM guest yesterday.
The hardware is kvm-intel enabled.   I tried the same thing on
Athlon64, but it does not have svm hardware enabled.   So qemu startup saying
/dev/kvm cannot be found, even though i had explicitly insmod kvm, and
dmesg show svm not enabled message.   But it is able to go through the
installation.

How can i debug via kvmtrace (or systemtap) to find out at which point it
hanged?   I gdb attached the hanging process (from host OS side), but
got a stuck at some select() in vl.c....not helpful.   Best will be a
debugging backtrace at the guest level, but then the guest is still midway
reading the iso images, and  then hang there.....no installation done
yet.

Thank you for the advice.
