This isn't the way this works: you select both fixed disks individually to be transferred during the conversion process, and the md0 device will be correctly handled at the other end. Can you give this another go? (In reply to comment #4) > This isn't the way this works: you select both fixed disks individually to be > transferred during the conversion process, and the md0 device will be correctly > handled at the other end. Can you give this another go? I am tring to use virt-p2v to convert both sda and sdb,as the disks are too large,it will take a long time to finish,now it just finished sda,I will update the result here once it finished. Converted both disks /dev/sda and /dev/sdb with virt-p2v,then the guest can be booted successful. Detail info after convert: 1. # df -h Filesystem Size Used Avail Use% Mounted on /dev/md0 9.9G 1.8G 7.6G 19% / tmpfs 1.8G 0 1.8G 0% /dev/shm 2.# fdisk -l Disk /dev/vda: 320.1 GB, 320072933376 bytes 64 heads, 32 sectors/track, 305245 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x49e2fd2f Device Boot Start End Blocks Id System /dev/vda1 * 2 10241 10485760 fd Linux raid autodetect Disk /dev/vdb: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x333c333c Device Boot Start End Blocks Id System /dev/vdb1 * 1 1306 10485760 fd Linux raid autodetect Disk /dev/md0: 10.7 GB, 10737344512 bytes 2 heads, 4 sectors/track, 2621422 cylinders Units = cylinders of 8 * 512 = 4096 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md0 doesn't contain a valid partition table 3.# lsmod | grep virtio virtio_balloon 4281 0 virtio_net 15773 0 virtio_blk 5692 4 virtio_pci 6653 0 virtio_ring 7169 4 virtio_balloon,virtio_net,virtio_blk,virtio_pci virtio 4824 4 virtio_balloon,virtio_net,virtio_blk,virtio_pci 4.# cat /boot/grub/device.map # this device map was generated by anaconda (hd0) /dev/vda (hd1) /dev/vdb The md0 only has 10G,but need to convert 640G(vda+vdb) to virt-p2v-server. Refer to comment 6,when converting physical machine installed on MD device,virt-p2v works by converting all the disks which make up the MD device(eg:sda and sdb),this should be documented. I tried rhel5 and rhel4 installed on MD device,then use virt-p2v to convert,after transferred the disk image,there is error from virt-p2v client:Invalid server response:mount_options:mount_options:mount_options_stub:/dev/md0:No such file or directory at /usr/share/perl5/vendor_perl/Sys/VirtConvert/GuestfsHandle.pm line 203, <> line 7. Checked the log file,there is error: /dev/md0: No such file or directory guestfsd: error: mount_options_stub: /dev/md0: No such file or directory virt-v2v: mkdtemp: mkdtemp: mkdtemp_stub: you must call 'mount' first to mount the root filesystem at /usr/share/perl5/vendor_perl/Sys/VirtConvert/GuestfsHandle.pm line 203, <> line 7. at /usr/share/perl5/vendor_perl/Sys/VirtConvert/Config.pm line 235 Created attachment 577204 [details]
Add the virt-p2v-server-md-error.log
Set LIBGUESTFS_TRACE=1 in /usr/bin/virt-p2v-server,attached the virt-p2v log file for converting physical machine installed on MD device.
The underlying cause seems to be that the mdadm_conf lens is missing from augeas in RHEL 6. (dev-acked on the understanding that Matt would do the packaging) Note that to use this you will require libguestfs 1.16.19-1.el6 (https://brewweb.devel.redhat.com/buildinfo?buildID=209687) Verified the bug with: virt-p2v-0.8.6-5.20120502.1.el6.iso virt-v2v-0.8.7-6.el6.x86_64 libvirt-0.9.10-16.el6.x86_64 libguestfs-1.16.19-1.el6.x86_64 augeas-0.9.0-3.el6.x86_64 Steps: 1.Download the virt-p2v iso from brewweb. 2.Create MD device /dev/md0 with sda and sdb. 3.Install rhel5 and rhel4 on md0. 4.Use virt-p2v to convert the host on md0,both rhel5 and rhel4 can be converted successfully without these error messages. So move the bug to VERIFIED. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
