I selected one virtual CPU for the XP load...primarily because I want to
run a couple more VMs and the guidance was to allocate one real CPU per
VM.
So far, I'm very impressed with kvm. However, I'm getting an SELinux
alert on qemu, and have posted the sealert txt to the selinux-list for
resolution. The VM seems to run ok, but I must do so as root, and not a
regular user. kvm+qemu on CentOS is supposed to be able to be run as a
regular user. The SELinux alert seems to revolve around the admin type
(or lack thereof). I'm hoping the SELinux gurus can work it out.
In the meantime, I need to figure out how to get the XP VM to access a
usb thumbdrive.
