One of our PVE servers hosts several OpenVZ and one freshly installed KVM VM, with a Windows Server 2008 R2 x64 guest (with latest VirtIO for net and disk).
Hardware is Q6600, 8GB RAM, mdraid on Intel SATA.
If more than one CPU core is enabled for the KVM VM, then it constantly eats 30% CPU even when idle.
When only one CPU core is enabled, it idles around 1-5%.
Is this related to DEP (Data Execution Prevention) or x64?
Is this going to get fixed? I remember that SMP has always been problematic with KVM, but thought this has been resolved.
Anyone else having this same problem?
