Output of virt-manager --debug
Debug output of virt-manager on my fedora box.
Please also provide /var/log/libvirt/qemu/$vmname.log from the VMs host. This error comes straight from qemu, so reassigning to RHEL7 qemu. There's another bug open with the same error (bug 953062) however that specifically mentions AHCI/q35 which your VM isn't using, so it must be something else Created attachment 916722 [details] qemu libvirt log-file (In reply to Cole Robinson from comment #2) > Please also provide /var(In reply to Cole Robinson from comment #2) > Please also provide /var/log/libvirt/qemu/$vmname.log from the VMs host. Hi Cole. No problem./log/libvirt/qemu/$vmname.log from the VMs host. I seem to have the same or a similar problem. My setup is simpler: host is Fedora 20, virt-manager runs on the host, VM runs CentOS7. However, I have the feeling that this has nothing to do with what runs in the VM.
The error message appears only when I attempt to snapshot a running VM. If the VM is shutdown, snapshotting is successful. The error is not related to a particular VM, newly created VMs are also affected. This is a regression introduced recently in the Fedora 20 packages (although I can't identify which one...) as 2-3 weeks ago snapshotting of a running VM was working; apart from installing updated packages, there were no changes in the setup of the host in the meantime.
The VMs are created with the following commands:
qemu-img create -f qcow2 -o preallocation=metadata ${VMNAME}-sda 8G
virt-install --accelerate --noautoconsole --name=${VMNAME} --ram=2048 --vcpus=1 --cpu host --disk path=${VMNAME}-sda,format=qcow2,bus=sata,cache=none --network=bridge=br0,mac=52:54:00:01:23:45 --graphics spice --location=http://mirror/centos/7/os/x86_64/ --extra-args="noselinux ks=http://install/ks.cfg"
Please let me know if further data would be helpful.
Bogdan, please open a bug against fedora qemu to track that issue, they might be the same root cause but the fedora and rhel qemu code bases are quite different. Still seeing this on a centos host using virt-manager on Fedora 23 as the client This bug is quite old, did id progress elsewhere? Still seeing this on a centos host using virt-manager on Fedora 23 as the client This bug is quite old, did it progress elsewhere? As it turns out this is caused by having a SATA bus attached to the VM. Removing that is the workaround.

Version-Release number of selected component (if applicable): virt-manager-1.0.1-3.fc20.noarch How reproducible: always Steps to Reproduce: 1. Install rhel7 server 2. Create windows 2008 virtual machine (xml config is attached) 3. Try to snapshot machine from virt-manager on fedora 20 Actual results: Error dialog box with: Error creating snapshot: operation failed: Error -22 while writing VM Details: Error creating snapshot: operation failed: Error -22 while writing VM Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 91, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/snapshots.py", line 466, in _do_create_snapshot self.vm.create_snapshot(xml) File "/usr/share/virt-manager/virtManager/domain.py", line 1053, in create_snapshot self._backend.snapshotCreateXML(xml, flags) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1788, in snapshotCreateXML if ret is None:raise libvirtError('virDomainSnapshotCreateXML() failed', dom=self) libvirtError: operation failed: Error -22 while writing VM Expected results: Snapshoted machine. Additional info: I'm able to snapshot all other machines on server.
