4:02 p.m.
I have a fairly large OVA (~200GB) that was exported from oVirt4.3.5. I'm trying to
import it into a new cluster, also oVirt4.3.5. The import starts fine but fails again and
again.
Everything I can find online appears to be outdated, mentioning incorrect log file
locations and saying virt-v2v does the import.
On the engine in /var/log/ovirt-engine/engine.log I can see where it is doing the
CreateImageVDSCommand, then a few outputs concerning adding the disk, which end with
USER_ADD_DISK_TO_VM_FINISHED_SUCCESS, then the ansible command:

Then nothing about the import until:

I've found the import logs on the engine, in /var/log/ovirt-engine/ova, but the
ovirt-import-ova-ansible*.logs for the imports of concern only contain:
2019-08-20 19:59:48,799 p=44701 u=ovirt | Using

Watching the host selected for the import, I can see the qemu-img convert process running,
but then the engine frees the lock on the VM and reports the import as having failed.
However, the qemu-img process continues to run on the host. I don't know where else to
look to try and find out what's going on and I cannot see anything that says why the
import failed.
Since the qemu-img process on the host is still running after the engine log shows the
lock has been freed and import failed, I'm guessing what's happening is on the
engine side.
Looking at the time between the start of the ansible command and when the lock is freed it
is consistently around 30 minutes.
# first try
2019-08-20 15:40:38,653-04 ansible command start
2019-08-20 16:11:08,859-04 lock freed
31 minutes
# second try
2019-08-20 19:59:48,463-04 ansible command start
2019-08-20 20:30:21,697-04 lock freed
30 minutes, 33 seconds
# third try
2019-08-21 09:16:42,706-04 ansible command start
2019-08-21 09:46:47,103-04 lock freed
30 minutes, 45 seconds
With that in mind, I took a look at the available configuration keys from engine-config
--list. After getting each the only one set to ~30 minutes and looks like it could be the
problem was SSHInactivityHardTimeoutSeconds (set to 1800 seconds). I set it to 3600 and
tried the import again, but it still failed at ~30 minutes, so that's apparently not
the correct key.
Also, just FYI, I also tried to import the ova using virt-v2v, but that fails
immediately:
virt-v2v: error: expecting XML expression to return an integer (expression:
rasd:Parent/text(), matching string: 00000000-0000-0000-0000-000000000000)
If reporting bugs, run virt-v2v with debugging enabled and include the
complete output:
virt-v2v -v -x [...]
Does virt-v2v not support OVAs created by the oVirt 'export to ova' option?
So my main question is, Is there a timeout for VM imports through the engine web UI?
And if so, is if configurable?
Thanks in advance.
7:45 p.m.
There is a default timeout for ansible, which is 30 minutes.
You may refer to:
https://bugzilla.redhat.com/show_bug.cgi?id=1528960
https://github.com/oVirt/ovirt-engine/blob/master/packaging/services/ovir...
"
# Specify the ansible-playbook command execution timeout in minutes.
It's used for any task, which executes
# AnsibleExecutor class. To change the value permanentaly create a
conf file 99-ansible-playbook-timeout.conf in
# /etc/ovirt-engine/engine.conf.d/
ANSIBLE_PLAYBOOK_EXEC_DEFAULT_TIMEOUT=30
"
Please try to create 99-ansible-playbook-timeout.conf in
/etc/ovirt-engine/engine.conf.d/ and set
ANSIBLE_PLAYBOOK_EXEC_DEFAULT_TIMEOUT=<Timeout>

Liran.
