avoid soft lockups
Hello, If I suspend and resume a guest under kvm, or I migrate it from one host to another, I sometimes get a soft lockup. Is there a timer mode to prevent or reduce the likelihood of these?

virt-install: hda disks?
Hi, Not sure if this is the right place to ask this. I'm getting hda disks by default with kvm under RHEL5.4 using virt-install. This seems an odd default. Is there a reason for hda disks over sda disks? Can I change this?
