Hello,
I am trying to run KVM machine from the image created as COW from the original
image. But it not working.
Screenshot that shows the KVM works with the original image
[r...@prasad images]# qemu-kvm /var/lib/libvirt/images/Ubuntu.img -m 512
^Z
[1]+ Stopped qemu-kvm /var/lib/libvirt/images/Ubuntu.img -m 512
[r...@prasad images]# bg
[1]+ qemu-kvm /var/lib/libvirt/images/Ubuntu.img -m 512 &
[r...@prasad images]# pwd
/var/lib/libvirt/images
[r...@prasad images]# lsmod | grep -i kvm
kvm_intel 42122 3
kvm 257132 1 kvm_intel
1. Created COW copy of the image after stoping the VM that was running
[r...@prasad images]# pwd
/var/lib/libvirt/images
[r...@prasad images]# qemu-img create -b Ubuntu.img -f qcow
/home/prasad/Virtual/Ubuntu_copy.ovl
2. Trying to run VM using the copy created
[pra...@prasad Virtual]$ ls -l
total 36
-rw-r--r--. 1 root root 32832 Nov 9 15:33 Ubuntu_copy.ovl
[pra...@prasad Virtual]$ qemu-kvm Ubuntu_copy.ovl -m 512
qemu: could not open disk image Ubuntu_copy.ovl: Permission denied
[pra...@prasad Virtual]$ sudo qemu-kvm Ubuntu_copy.ovl -m 512
qemu: could not open disk image Ubuntu_copy.ovl: No such file or directory
[pra...@prasad Virtual]$ sudo qemu-kvm ./Ubuntu_copy.ovl -m 512
qemu: could not open disk image ./Ubuntu_copy.ovl: No such file or directory
[pra...@prasad Virtual]$ qemu-kvm ${PWD}/Ubuntu_copy.ovl -m 512
qemu: could not open disk image /home/prasad/Virtual/Ubuntu_copy.ovl:
Permission denied
[pra...@prasad Virtual]$ sudo qemu-kvm ${PWD}/Ubuntu_copy.ovl -m 512
qemu: could not open disk image /home/prasad/Virtual/Ubuntu_copy.ovl: No such
file or directory
Why is it failing?
Thanks and Regards,
Prasad Joshi
