Can you please try converting just 1 of these disks? I suspect that will work. If so, this would require documentation. Hi matt, I have tried as you comment. There are two disks /dev/sdb and /dev/sdd in p2v "Fixed Storage". 1. Convert /dev/sdd,there is a error "Error reading data in send_data:Input/ouput error" #dmesg ... end_request: I/O error, dev sdd, sector 0 __ratelimit: 10 callbacks suppressed Buffer I/O error on device sdd, logical block 0 Buffer I/O error on device sdd, logical block 1 Buffer I/O error on device sdd, logical block 2 Buffer I/O error on device sdd, logical block 3 Buffer I/O error on device sdd, logical block 4 Buffer I/O error on device sdd, logical block 5 Buffer I/O error on device sdd, logical block 6 Buffer I/O error on device sdd, logical block 7 Buffer I/O error on device sdd, logical block 8 Buffer I/O error on device sdd, logical block 9 sd 4:0:3:0: [sdd] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sd 4:0:3:0: [sdd] Sense Key : Illegal Request [current] sd 4:0:3:0: [sdd] <<vendor>> ASC=0x94 ASCQ=0x1ASC=0x94 ASCQ=0x1 sd 4:0:3:0: [sdd] CDB: Read(10): 28 00 00 00 00 00 00 00 08 00 end_request: I/O error, dev sdd, sector 0 ... 2.Convert /dev/sdb successfully,the guest can boot. But the device.map didn't update. # cat /boot/grub/device.map # this device map was generated by anaconda (hd0) /dev/mapper/mpatha ===> For this problem,I will create another bug if this bug is documented. 3.On host,check the multipath device. # multipath -ll ...... 3600a0b80005adb0b000060d04f775e1c dm-1 IBM,1726-4xx FAStT size=20G features='1 queue_if_no_path' hwhandler='1 rdac' wp=rw |-+- policy='round-robin 0' prio=6 status=active | `- 4:0:2:0 sdb 8:16 active ready running `-+- policy='round-robin 0' prio=1 status=enabled `- 4:0:3:0 sdd 8:48 active ghost running The sdb is active ready running and sdd is active ghost running.

Typo.Here it should be sdd fail.
