[kvm-devel] virtio: kvm-62, lilo cannot be installed into virtio device
Hello I test virtio block device. I can boot from vda as root partition, but if I want to install lilo into boot sector, lilo give me this error: Fatal: Linux experimental device 0x04x needs to be defined. Check 'man lilo.conf' under 'disk=' and 'max-partitions=' I boot it like this: kvm -boot c -drive file=basic-virtio.qcow2,if=virtio,boot=on -m 512 -vnc :0 -net nic,model=virtio,vlan=0,macaddr=00:00:10:52:37:48 -net tap,vlan=0,ifname=tap0,script=no -daemonize -localtime basic-virtio.qcow is with lilo in boot sector installed, because is image what I use before virtio testing. But with each boot I must manually add root=/dev/vda2 if I want to boot it. Host: Gentoo, kernel with gentoo patchset 2.6.24-r3 Guest: Gentoo, kernel vanilla 2.6.25-rc3 KVM: 62 qemu: 0.9.1 Thank you for your job. -- Tomas Rusnak, Korex Networks Korex s.r.o.

Thank you for your quick answer, but this doesn't help. After i run lilo, it give me the same error message. -- Tomas Rusnak, Korex Networks Korex s.r.o.

After this I try max-partitions=7 and run lilo with following result: Warning: /proc/partitions references Experimental major device 254. Warning: /proc/partitions references Experimental major device 254. Warning: /proc/partitions references Experimental major device 254. Added Gentoo-25 * 3 warnings were issued. Now I can boot it correctly. Thank you very much again. -- Tomas Rusnak, Korex Networks Korex s.r.o.

I suggested 16 because that's what the called to alloc_disk in the virtio block driver is using. I'm not sure why lilo dislikes that value. Now I can boot it correctly. Thank you very much again. It might be useful to put up a Wiki page now that you have it working for this. - This SF.net email is sponsored by: Microsoft Defy all challenges.

It might be useful to put up a Wiki page now that you have it working for this. It's no problem to publish it for others, but did you mean to update this page? http://kvm.qumranet.com/kvmwiki/Virtio?highlight=%28virtio%29/edit or make a new page? I don't know how, because I never put something onto kvm wiki. Can you point me to right way? :) -- Tomas Rusnak, Korex Networks Korex s.r.o.

Added Gentoo-25 * 3 warnings were issued. max-partitions=7 sounds a bit confining, why are we using such a low number? LILO is one of several reasons why using dynamic major really isn't such a great idea. We don't have the 8:8 limitation anymore. -hpa - This SF.net email is sponsored by: Microsoft Defy all challenges.
