Testing Results for TPR optimization tarball

Testing Results for TPR optimization tarball

[Anthony Liguori]

With the patch to increase the minimum rmap cache, I've been able to 
successful install and boot with kvm-test:

Windows XP Professional (i386)
Windows Vista Enterprise Edition (i386)
Fedora 8 test 3 (i386)
openSUSE 10.3 (x86_64)
RHEL5 Server (x86_64)
SLES10 (x86_64)
Ubuntu 6.06.1 server (i386)
Ubuntu 7.04 desktop (x86_64)
Ubuntu 7.10 desktop (i386)

It's looking pretty good to me.

Regards,

Anthony Liguori

Were you able to do this with -smp 2 or more?

I haven't tried doing smp testing yet.  But I can do that now.

I get a BSOD with -smp 2.  But I haven't yet been able to confirm that 
this is a regression.

Since the TPR optimization makes the install go over 2x as fast, it's 
throwing off my automated tests.

I don't think it's a regression.  With the latest git, I cannot install 
Windows XP with -smp 2.

You can convert an installation that was performed with one cpu to smp
by starting the VM with -smp 2.
