Public bug reported:
Hi bug masters,
I have a Ubuntu 9.04 server running virtualization with many guests. The
guests are defined by an xml file (attached) in /etc/libvirt/qemu and
started by virsh start "domain name". The guests are using a qcow2
type disks. I want to upgrade this server to Ubuntu 10.04.1 LTS and to
test if all my guests can be safely migrated over to new server I have
installed lucid in a similar server and copied over the disk image and
config xml. I created the domain using virsh create "domain xml file"
(after making changes to IP address, mac address and source file
location). When I start the VM using virsh start "domain name" I get
an error in the vnc console (screen shot attached).
The disk image I copied from old server is running fine in that server.
I have also tried with another disk image, in case the first image is
corrupted, and result is the same.
Actual kvm command in the new server (lucid) is as follows:
/usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 256 -smp 1 -name a1.6-q2 -uuid
9f58079c-057f-5726-4daa-3d30888d7bbe -chardev
socket,id=monitor,path=/var/lib/libvirt/qemu/a1.6-q2.monitor,server,nowait
-monitor chardev:monitor -localtime -boot c -drive
file=/var/kvm/a1.6-q2.img,if=ide,index=0,boot=on,format=raw -net
nic,macaddr=52:54:00:13:34:42,vlan=0,name=nic.0 -net
tap,fd=42,vlan=0,name=tap.0 -chardev pty,id=serial0 -serial
chardev:serial0 -parallel none -usb -vnc 192.168.3.7:42 -vga cirrus
In old server (jaunty):
/usr/bin/kvm -S -M pc -m 384 -smp 1 -name alex2 -uuid 4c949839-9c2d-6c31
-8bfb-1b0b0504f92e -monitor pty -pidfile
/var/run/libvirt/qemu//alex2.pid -localtime -boot c -drive
file=/usr/local/var/kvm/alex2.img,if=ide,index=0,boot=on -net
nic,macaddr=52:54:00:12:34:49,vlan=0 -net
tap,fd=28,script=,vlan=0,ifname=vnet6 -serial pty -parallel none -usb
-vnc 192.168.3.3:49
One difference I noted was that the -drive option has an extra argument
"format=raw" which looks odd because the image I am using is qcow2 in
format.
Running the kvm command line directly from console in new server
resulted in the following error:
/usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 256 -smp 1 -name a1.6-q2 -uuid
9f58079c-057f-5726-4daa-3d30888d7bbe -chardev
socket,id=monitor,path=/var/lib/libvirt/qemu/a1.6-q2.monitor,server,nowait
-monitor chardev:monitor -localtime -boot c -drive
file=/var/kvm/a1.6-q2.img,if=ide,index=0,boot=on -net
nic,macaddr=52:54:00:13:34:42,vlan=0,name=nic.0 -net
tap,fd=42,vlan=0,name=tap.0 -chardev pty,id=serial0 -serial chardev:serial0
-parallel none -usb -vnc 192.168.3.7:42 -vga cirrus
char device redirected to /dev/pts/4
TUNGETIFF ioctl() failed: Bad file descriptor
TUNSETOFFLOAD ioctl() failed: Bad file descriptor
pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin"
So I could not test with "format=qcow2" in -drive option.
Pl let me know if any further information is required to traig this
issue.
with regards,
raj
