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 start 103
Domain 103 started
#vzlist
CTID NPROC STATUS IP_ADDR HOSTNAME
103 20 running - -
3) Check memory size vz guest 103
#vzctl enter 103
