Hello,

Kindly CC me in your replies, I'm not a subscriber.


Is renaming qcow2 images prohibited?
My VM behaves differently (hangs when boot is complete) after copying the image.


sudo taskset 3 /usr/bin/kvm -m 1024 -hda  test2-deb32-net.qcow  -net
nic,model=rtl8139,macaddr=52:54:00:00:00:15 -net
tap,vlan=0,ifname=tap15
-> Original image, this works fine.

cp test2-deb32-net.qcow nxserver.qcow
-> Only after the image was shut down of course...

sudo taskset 3 /usr/bin/kvm -m 1024 -hda nxserver.qcow  -net
nic,model=rtl8139,macaddr=52:54:00:00:00:15 -net
tap,vlan=0,ifname=tap15
-> Completes full boot sequence, but instead of throwing getty it
somehow freezes (still unsure as to why)

rm nxserver.qcow
qemu-img convert  test2-deb32-net.qcow -O qcow2 nxserver.qcow2
-> This new nxserver.qcow2 image works perfectly once again.


All images were created as qcow2 (ignore file extensions), but
interestingly the original image is somehow recognised as "raw"
format...
image: test2-deb32-net.qcow
file format: raw
virtual size: 10G (10737418240 bytes)
disk size: 652M


I've also noticed this with win2003 guest images.

I'm probably missing something or doing something stupid - I'd be glad
if someone can point it out.


Kind regards,
Joris
