Subject: [Users] oVirt Node (HyperVisor) - Memory Usage
Hi All,
I've just had a little check on a hyper-visor (based on Centos 6.3)
VDSM versions:
vdsm.x86_64 4.10.0-0.44.14.el6
vdsm-cli.noarch 4.10.0-0.44.14.el6
vdsm-python.x86_64 4.10.0-0.44.14.el6
vdsm-xmlrpc.noarch 4.10.0-0.44.14.el6
BUT - my concern is more that a VMs virtual memory (VSZ) allocation is much
higher than that of its configuration ?
qemu 24233 11.0 1.0 *3030420* 1008484 ? Sl 2012 2189:02
/usr/libexec/qemu-kvm -S -M rhel6.3.0 -cpu Conroe -enable-kvm *-m
2048*-smp 4,sockets=1,cores=4,threads=1 -name

Alex,
What usage do you see and what did you configure?

qemu 24233 11.0 1.0 *3030420* 1008484 ? Sl 2012 2189:02
/usr/libexec/qemu-kvm -S -M rhel6.3.0 -cpu Conroe -enable-kvm *-m
2048*-smp 4,sockets=1,cores=4,threads=1 -name
above example shows ~3 Gig VSZ but only 2048m are actually configured ...
if i'm not too blind and dumb :) ... 3030420 kb = 2959.39 mb ... and that's
not what is configured as the VMs max allowed ram ...

Hi Alex,
Interesting, we'll need to look into it.
Do you mind opening a BZ? I'll see that it's routed to the relevant people.
Thanks!
Doron

I am not suggesting that 1GB qemu overhead is not interesting, but I do
not think this list is the best place to find the answer. I suggest that
you specify the libvirt and qemu versions, and take the question - and
the bug - to qemu-devel(a)nongnu.org.
Ta!
