Hi All,
Trying to use qemu-img-xen from xen-4.0-testing to convert some raw disk
images to qcow2.
xen5 var # qemu-img-xen convert -f raw -O qcow2 nathanxen_tmp
nathanxen_tmp.qcow2
qemu-img: error while writing
Strace shows that qemu-img-xen is opening the file properly, writing a
bunch, then closing it and reopening it as readonly before trying to
write more to it? Someone know what the deal is here?
Thanks,
Nathan
