(I am running 4.4.9 and node 4.4.8, I don't node is built yet for .9) The issue I am having is changing CDs, when I try to change it get the following error: (Both ISOs are uploaded though the GUI on block storage, iSCSI) GUI: Error while executing action Change CD: Failed to perform "Change CD" operation, CD might be still in use by the VM. Please try to manually detach the CD from withing the VM: 1. Log in to the VM 2 For Linux VMs, un-mount the CD using umount command; For Windows VMs, right click on the CD drive and click 'Eject'; LOG: ERROR FINISH changeCD error=Failed to change disk image Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 5005, in _update_disk_device disk_xml, libvirt.VIR_DOMAIN_DEVICE_MODIFY_FORCE) File "/usr/lib/python3.6/site-packages/vdsm/virt/virdomain.py", line 101, in f ret = attr(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/function.py", line 94, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python3.6/site-packages/libvirt.py", line 3237, in updateDeviceFlags raise libvirtError('virDomainUpdateDeviceFlags() failed') libvirt.libvirtError: internal error: unable to execute QEMU command 'blockdev-add': 'file' driver requires '/rhev/data-center/mnt/blockSD/XX/images/XX/XX' to be a regular file During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 124, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/API.py", line 153, in changeCD return self.vm.changeCD(driveSpec) File "<decorator-gen-281>", line 2, in changeCD File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 101, in method return func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 4768, in changeCD self._change_cd(blockdev, drive_spec, iface, force=force) File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 5049, in _change_cd self._update_disk_device(disk_xml, force=force) File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 5008, in _update_disk_device raise exception.ChangeDiskFailed()#012vdsm.common.exception.ChangeDiskFailed: Failed to change disk image I feel like I have see a couple bugs on this, but now I can't find them...
