well, some time it does take a long time. Are you sure it was hung?

The most likely reason for virt-v2v to hang (actually it's qemu which
is hanging) is that you've run out of disk space. Most probably in
/var/tmp but best to check all your host filesystems.
No, the filesystem had plenty of space.
It eventually did complete, after several hours. But I don't understand
why this particular VM took so long when others (with similar disk
sizes/usages/configurations) completed in only 1-2 minutes. Each VM is
effectively exactly the same (it's a build slave), so it's just the
basic installation of the particular Fedora release, the build tools,
and the build slave configuration. Beyond the underlying fedora release
version, the systems are configured exactly the same.
I migrated four similar VMs. Three of them completed almost
immediately. The last too much longer. The ONLY thing different about
the one that took longer was that I decided to pack the disk first, so I
ran:
vmware-toolbox-cmd disk shrink /
in the VM prior to packaging it up as an OVA. All the OVA files are
relatively small and similar in size:
-rw------- 1 warlord warlord 1959553024 Nov 7 10:40 fc20-64.ova
-rw------- 1 warlord warlord 1794907648 Nov 7 12:27 fc21-64.ova

The FC23 and FC22 migrations took the least amount of time, even though
they were the largest.

I'm not familiar with this command. In general terms, conversions
take a time proportional to the amount of disk space in use by the
guest.
This command is a disk defragment + shrink inside VMware. Basically, the
.vmdk was about 36G even though the system was only using about 3G.
Running this command released all that free space and then reduced the
VMDK file.
I figured the time should be proportional to disk usage, which is why I
was so surprised that it took orders of magnitude longer than other
systems with similar disk usage (and indeed, in some cases the other
systems that completed in minutes had MORE disk usage).
Running `virt-v2v -v -x ...' and observing the output will give
you a
good idea of what precisely it was doing for those hours.
Well, as I said in my original email, it was hanging at running setfiles:
commandrvf: stdout=n stderr=y flags=0x0
commandrvf: setfiles -F -e /sysroot/dev -e /sysroot/proc -e
/sysroot/selinux -e /sysroot/sys -r /sysroot -q
/sysroot/etc/selinux/targeted/contexts/files/file_contexts /sysroot/
Can't stat exclude path "/sysroot/selinux", No such file or directory
- ignoring.
There's no timestamp in the output or logs so it's hard to tell exactly
what happens when or how long each step takes. For example, I wouldn't
know how long the setfiles step takes unless I sit there for hours
watching to see when it completes. Is there some way to add timestamps to
each output line?
FWIW, here's the disk usage from within that VM:
Filesystem Size Used Avail Use% Mounted on
/dev/vda3 44G 4.6G 37G 12% /
devtmpfs 487M 0 487M 0% /dev
tmpfs 497M 0 497M 0% /dev/shm
tmpfs 497M 348K 496M 1% /run
tmpfs 497M 0 497M 0% /sys/fs/cgroup
tmpfs 497M 4.0K 496M 1% /tmp
/dev/vda1 969M 130M 773M 15% /boot
tmpfs 100M 0 100M 0% /run/user/1000
tmpfs 100M 0 100M 0% /run/user/0
For the record, Fedora 23, which imported in 2 minutes, has the following
disk usage:
Filesystem Size Used Avail Use% Mounted on
devtmpfs 486M 0 486M 0% /dev
tmpfs 496M 0 496M 0% /dev/shm
tmpfs 496M 536K 496M 1% /run

Well, as I said in my original email, it was hanging at running setfiles:

OK that's interesting. setfiles is doing SELinux labelling of the
filesystem. The time taken should be approximately proportional to
the number of files in the filesystem.
What it precisely does is to run the host's /usr/sbin/setfiles command
over the whole guest filesystem, using the guest's
/etc/selinux/targeted/contexts/files/file_contexts to control the
labelling. So if either of the guest filesystem or the guest's
file_contexts is particularly large, or setfiles has a bug, then it
might take a long time.
There's no timestamp in the output or logs so it's hard to

Yes, this is conclusive.
The guest is Fedora 21? Does it have an unusually large number of
files in the filesystem? Is the host RHEL or Fedora and which

I will see if I can reproduce it.

files in the filesystem? Is the host RHEL or Fedora and which
version?
Guest is Fedora 21. Host is CentOS 7.2
Guest not have an unusual number of files. At least looking at the number
of inodes used:
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/vda3 2894304 164989 2729315 6% /
So... 165,000 files? My F23 system which imported in 2 minutes has
174,442 inodes used, albeit significantly more free:
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/vda3 23080448 174442 22906006 1% /
Another difference is ext4 (F21) vs xfs (F23).
I will see if I can reproduce it.
Thanks. Worst case I can probably provide you the OVA.

I'll try to reproduce the issue here, but you can also do
the following command directly on the guest disk image if you
want to test something:
time LIBGUESTFS_BACKEND=direct guestfish --ro -a fc21-64.qcow2 -i selinux-relabel
/etc/selinux/targeted/contexts/files/file_contexts / force:true
As long as you make sure you use the '--ro' flag, this will not make
any changes to the disk image.
For me that command only takes ~15 seconds to run on a Fedora 21 disk
image with minimal (@Core) packages installed. I'm using a
RHEL 7.3 host.

The OVA has a .vmdk file inside it. I have no idea where ovirt put the

Can I run this command on the disk image of a running VM that's already

So noted. Like I said, I can supply you the ova file if you think it
would help. It's only 1.7GB ;)

The OVA has a .vmdk file inside it. I have no idea where ovirt put the
.qcow2 file. I suppose I would need to track it down through the VM GUID?
Safest and easiest would be to run the command on the .vmdk file. The
command creates an overlay and works in roughly the same was as
virt-v2v itself does.
Can I run this command on the disk image of a running VM that's
already
been imported?
As long as you use --ro it's safe to use. However I'd suggest running
it on the source .vmdk to be as close as possible to what virt-v2v was
doing.

would help. It's only 1.7GB ;)
Let's see if this command takes a long time first. It could be the
cause is elsewhere.

Safest and easiest would be to run the command on the .vmdk file. The
command creates an overlay and works in roughly the same was as
virt-v2v itself does.

As long as you use --ro it's safe to use. However I'd suggest running
it on the source .vmdk to be as close as possible to what virt-v2v was
doing.

Let's see if this command takes a long time first. It could be the
cause is elsewhere.
I found the disk image for the running VM, created a symlink, and then ran
the command above. It took a while:
# time LIBGUESTFS_BACKEND=direct guestfish --ro -a fc21-64.qcow2 -i
selinux-relabel /etc/selinux/targeted/contexts/files/file_contexts /
force:true
real 114m17.757s
user 114m16.476s
sys 0m6.042s
I could do it off the vmdk if you wish, but I'm sure there haven't been
many significant changes to the VM since it was imported. Besides, I
suspect it wouldn't change the outcome of the test.

That certainly demonstrates the bug. I'm unclear why it would be
happening, but perhaps you can run the following commands and send me
the results:
LIBGUESTFS_BACKEND=direct guestfish --ro -a fc21-64.qcow2 -i find / > files
LIBGUESTFS_BACKEND=direct virt-cat -a fc21-64.qcow2
/etc/selinux/targeted/contexts/files/file_contexts / > file_contexts
rpm -qf /usr/sbin/setfiles > setfiles.version
Note that the first command produces a list of all filenames within
the virtual machine, which might be sensitive information, so you may
wish to send me that file privately.
Thanks,
Rich.

See attached.. There are 184,431 entries in the file list.
rpm -qf /usr/sbin/setfiles > setfiles.version
Did you want this on the host or in the guest? On the host I get:
policycoreutils-2.2.5-20.el7.x86_64
On the guest:
policycoreutils-2.3-7.1.fc21.x86_64
Note that the first command produces a list of all filenames within

There's really nothing private in the list of files on this machine. It's
an openafs build slave. :)
Thanks,
Rich.
Thank you..

Did you want this on the host or in the guest? On the host I get:
policycoreutils-2.2.5-20.el7.x86_64
This is the same version I have.
There's really nothing private in the list of files on this
machine. It's
an openafs build slave. :)
Indeed there's a large number of .ccache files (over 50000).
However even recreating this directory structure locally and using the
same version of setfiles, I wasn't able to reproduce the problem.
Runs of setfiles never took more than about 15 seconds.
So, I don't know ..

But that shouldn't be an issue, right? In the scheme of things, 50,000
files isn't a lot.
However even recreating this directory structure locally and using
the
same version of setfiles, I wasn't able to reproduce the problem.
Runs of setfiles never took more than about 15 seconds.
So, I don't know ..
Would you like a copy of the VMDK? If so I can figure out how to make it
available to you (privately).

Thanks for supplying the disk image.
I am able to reproduce this with the version of setfiles in RHEL 7.3,
but not with the version in Fedora 24, so I guess this was fixed
somewhere in between.
I'll try to narrow it down to a particular commit and send a bug
report.

Oh, so it's setfiles on the HOST that gets run, not setfiles within the
guest? Interesting.

Can you please CC me on the bug report once you send it?

Or I can CC myself if you supply me the bug#.
