Issues to manage RAM on openvz guests
Hi all,
I'm playing with virsh, and I succeed to mange easily some KVM nodes.
But I have issues to size RAM of openvz guests.
virsh set by default the the memory to 256M on each guest instead of that I
specify in the XML
I have to modify by end the variable PHYSPAGES on each
/etc/vz/conf/id_of_my_vz.conf
Please follow the XML dump and the steps that I did.
Cheers,Aurelien

----
1) Define openvz guest domain 103
#virsh -c openvz:///system define vztest.xml
Domain 103 defined from vztest.xml
2) Start the guest
#virsh -c openvz:///system star...

status of autotuning freebsd for 9.2
Andre,
Are you going to have time to MFC things from -current for auto-tuning
-stable before 9.2?
I fear (maybe unnecessarily?) that we are about to ship yet another
release that can't do basic 10gigE when sufficient memory exists.
If you don't have time, then let me know and I'll see what I can do.

[RFC/PATCH 00/15] kvm on big iron
This patch series introduces a backend for kvm to run on IBM System z
machines that uses the mainframe's sie virtualization capability. This
work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with
a 64bit linux host. Userspace will follow once we're done brushing it
over.
The patch queue consists of the following patches, which can be applied
in sequence on top of kvm.git
