?Hi, I have maybe a strange thing on a nodedev-dumpxml virsh result : virsh # nodedev-dumpxml block_sr0 <device> <name>block_sr0</name> <parent>scsi_0_0_1_0</parent> <capability type='storage'> <block>/dev/sr0</block> <bus>scsi</bus> <drive_type>cdrom</drive_type> <model>DVD RW DRU-190S</model> <vendor>SONY</vendor> <capability type='removable'> <media_available>0</media_available> <media_size>0</media_size> </capability> </capability> </device> I think (note I'm not sure), the capabilty type removable should be in the device element, like this : virsh # nodedev-dumpxml block_sr0 <device> <name>block_sr0</name> <parent>scsi_0_0_1_0</parent> <capability type='storage'> <block>/dev/sr0</block> <bus>scsi</bus> <drive_type>cdrom</drive_type> <model>DVD RW DRU-190S</model> <vendor>SONY</vendor> </capability> <capability type='removable'> <media_available>0</media_available> <media_size>0</media_size> </capability> </device> Let me know if I'm wrong.
