I've have setup a couple virtual machines and they work great... for anywhere
between 2-24 hours. But then, for no reason I can determine, they just go 100%
busy and stop responding.
My basic setup is:
Ubuntu 8.10 server running on both host and guests.
kvm version is the one from the Ubuntu distribution (kvm-72)
Kernel is Ubuntu 8.10 kernel (2.6.27-7-server)
The two VMs are both run like:
kvm -daemonize \
-hda Imgs/ndev_root.img \
-m 1024 -cdrom ISOs/ubuntu-8.10-server-amd64.iso \
-vnc :1 -net nic,macaddr=DE:AD:BE:EF:04:04,model=e1000 \
-net tap,ifname=tap1,script=/home/chris/kvm/qemu-ifup.sh
(With different disk imgs, vnc addresses and macaddrs)
The disk images are raw format:
qemu-img create -f raw 80G Imgs/ndev_root.img
I've tried running with these options, and in different combos:
-no-kvm-pit
-no-kvm-irqchip
-no-acpi
They don't seem to help much. If anything, -no-kvm-irqchip seems to cause more
troubles.
I tried running with -no-kvm and it won't boot at all.
I also built my own 2.6.27.4 kernel, from kernel.org, and built my own version
of kvm-78, but saw the same behavior.
Anyone have any advice how I can resolve these hangs? When the setup works,
it's a beautiful setup and I love kvm. But with the 100% busy hangs I can't
really continue with it.
Thanks!
Chris
