Hi guys, I hope you can help me on this issue with kvm/libvirt: using this command to install a kvm virtual machine: virt-install --connect qemu:///system \ --name p3k0401 \ --ram 2048 \ --file //dev/VolGroup01/p3k0401logvol \ --accelerate \ -s 10 \ --nographics \ --hvm \ --location='http://10.1.4.80' I get: Starting install...

Power Management and dom0 cpus
by Ben M. 27 Jul '10

27 Jul '10

["Standard" CentOS 5.5 Xen Virtualization installation.] I'm setting up a new box on AMD Opteron platform. I'm doing some preliminary baselines (no domUs running) with an inline Watt/VA meter. It appears to enable full power management Xen dom0 must have all cpus by not limiting in kernel statement nor in xendconfig.sxp. In previous installations I cut them back to 1 or 2. The bonus of all cpus appears to be a 16% to 20% reduction in wattage/va consumption at idle. Pretty substantial when I consider that my electric utility rates have increased 75% (yep) in the past two years alone. My question is to anyone with experience with this is will I be seeing a significant performance hit on domU performance in either paravirtualized or fully virtualized guests (or both)?
