[Libguestfs] virt-v2v F18 guest on F18 failure

Run with LIBGUESTFS_ATTACH_METHOD=appliance 

Fails with: 

inspect_os: mount_ro: /dev/sda on / (options: 'ro'): mount: /dev/sda is
already mounted or /sysroot busy at
      /usr/share/perl5/vendor_perl/Sys/VirtConvert/GuestfsHandle.pm line 194.

virt-inspector works as expected

libguestfs-test-tool.log: http://pastebin.ca/2317900
virt-v2v.log: http://iaindb.pastebin.ca/2317938

Any suggestions?

Can you please post the output run with LIBGUESTFS_TRACE=1?

Thanks,

The error is pretty strange.  Neither /dev/sda nor /sysroot get
mounted before the point where the error happens, so I can't
understand why the appliance kernel would think they are busy.

If virt-inspector works, that would suggest that it's not an error
with inspection.

Did you run virt-inspector with LIBGUESTFS_ATTACH_METHOD=appliance set?

Is this a one-off error or does it happen every time you run virt-v2v?

[Libguestfs] virt-v2v F18 guest on F18 failure

I think I've *discounted* IDE as a potential problem:

  $ rm /tmp/test1.img
  $ truncate -s1G /tmp/test1.img
  $ guestfish <<EOF
  set-attach-method appliance
  add-drive-opts /tmp/test1.img iface:ide readonly:true
  run
  mount /dev/sda /
  EOF
  libguestfs: error: mount: /dev/sda on / (options: ''): mount: wrong fs
type, bad option, bad superblock on /dev/sda,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

(the expected error)

vs:

  $ guestfish <<EOF
  set-attach-method appliance
  add-drive-opts /tmp/test1.img iface:ide readonly:true
  run
  mkfs ext2 /dev/sda
  mount /dev/sda /
  EOF

(no error)

Also tried:

 - Adding name:vda

 - Running isoinfo-device before the mount.

 - Running vfs-type before the mount.

I still couldn't reproduce this.

Rich.

194.
util-linux prints this when the mount syscall returns -EBUSY.

The man page for mount(2) gives these reasons:

EBUSY
  source is already mounted.
  [probably not]

  Or, it cannot be remounted read-only, because it still holds files
  open for writing.
  [while we are mounting r/o, we're not *re*mounting, and in any case
  we shouldn't have any files open for write]

  Or, it cannot be mounted on target because target is still busy (it
  is the working directory of some thread, the mount point of another
  device, has open files, etc.).
  [Could some other process have /sysroot open?  The only candidate
  is udev.]

I also looked at the Linux kernel code to see if there are any other
reasons why do_mount would return -EBUSY.  The only obvious ones are:

 - remounting read-only with files open for write

 - mounting the same filesystem a second time on the same mountpoint

 - mountpoint has open files, current working directories, chroots
   or sub-mounts

None of these seem as if they are likely reasons.

Rich.
