Hi,
To provide an emergency off-site backup server for a client, I'm trying
to use kvm on a nightly rsync'ed copy of their server. To avoid the use
of a disk image I was advised to try nfsroot. This the command I am
running:
# kvm -nographic -hda ~/empty.qcow2
-kernel /boot/vmlinuz-2.6.25.7-1-pyrrhus64
-append "3 root=/dev/nfs
nfsroot=10.0.3.1:/backup/client.server.com/current/ ip=dhcp
console=ttyS0 early_printk=ttyS0" -serial stdio -net nic -net
tap,script=/etc/kvm/kvm-ifup-zenon -m 1024
wich mostly works, the remaining problems I have are:
1) the nfsroot fs stays 'readonly' even though I modified the backup's
fstab to read:
10.0.3.1:/backup/client.server.com/current / nfs defaults,rw 0 0
try sticking a 'mount -o remount,rw /' somewhere in the boot initscripts.
2) the boot lingers a long time after "activating swap" even though
there is no swap entry in the modified fstab
3) the login: prompt is not reached, the kernel hangs at:
Running local boot scripts (/etc/rc.local).
Try to find out what it's doing there with some echos. It may be due to
the root filesystem being readonly.
4) also I'm not sure what the "console=" and "early_printk=" do; is it
at the nfsroot or kvm level?
These are Linux kernel options, see Documentation/kernel-parameters.txt.
