Re: CPU Limits on KVM?

There's CPU cgroups. It doesn't have exactly the ability you are after, but it is able to limit process(es) CPU usage. Maxing out CPU usage won't crash your server. The kernel will arbitrate sharing the CPU evenly among processes/VMs. --Brian Jackson On Thursday 02 April 2009 16:41:10

I don't think the kvm-guest-drivers are still well maintained (they haven't been touched in 5 months). If you are using kernel 2.6.29, it already has virtio drivers and you don't need the kvm-guest-drivers tree at all. --Brian Jackson On Wednesday 01 April 2009 23:10:43 Zhiyong Wu wrote: HI

If you use -vnc, then KVM runs and just sits there on the command line. It doesn't prompt you when it's ready or anything. So you can connect via VNC as soon as you start KVM. You connect with VNC just like you normally would to a server running a regular VNC server. --Brian Jackson

Don't use kvm in the tarball. It's not what you want. That's just a wrapper that calls qemu/kvm (possibly even the system one) after it mangles some command line options. Use qemu/x86_64-softmmu/qemu-system-x86_64 from the tarball if you aren't going to install it. Then you just use the same
