[ovirt-users] template mystery

2016-04-17 Thread Campbell McLeay 
Hi,

I've got 4 VMs on a 3.6 cluster, and they are listed as based on a
template called 'sl6-workstation', yet I cannot find this template
anywhere listed in the templates tab or tree. When I go to create a
new VM, it gives me the option in the template section to use:

sl6-workstation(1)

or

sl6-workstation(latest)

I'm not sure what the difference between these two are, but I'm
curious why it doesn't give me the option of not to use a template. It
will even be the only option if I select FreeBSD or some other non-sl6
OS.

Any ideas?

Thanks,

Cam

Re: [ovirt-users] backup-engine 3.6.4.1-1 Files Compressor still broken in Centos 6.7? Work around

2016-04-17 Thread Jack Greene 
Of course, I meant "annoying" in a good way ;)

Yep, 'xz' was missing, libs were there but not the compressor

[root@engine1 ~]# rpm -qa | grep xz
xz-libs-4.999.9-0.5.beta.20091007git.el6.x86_64

Installed package xz 

[root@engine1 ~]# rpm -qa | grep xz
xz-4.999.9-0.5.beta.20091007git.el6.x86_64
xz-libs-4.999.9-0.5.beta.20091007git.el6.x86_64

Backup worked like a charm.  Cheers

Well, I hope you prefer that over not be able to restore you engine if it dies 
:-)

Believe me, this was done after real people lost data and time, not because 
anyone found it fun to do.

Perhaps it's because you do not have 'xz' installed, and engine-backup defaults 
to use xz for the --files-compressor?

It will be fixed in 3.6.5, where engine-backup is packaged separately, with 
proper 'Require:' lines in the spec file:

https://bugzilla.redhat.com/show_bug.cgi?id=1320092
https://gerrit.ovirt.org/55045

Please try installing 'xz' and run engine-backup again. If it fails, please 
report back. Thanks.

That's an option too.

And you do not loose much by using it, because the files tar is compressed 
anyway when the archive is compressed, using gzip by default. 'files' are 
usually very small, compared to the databases, so the difference is not 
significant.

Seems like a bug in the documentation. See also the README file:

/usr/share/doc/ovirt-vmconsole/README on your machine, or

https://gerrit.ovirt.org/gitweb?p=ovirt-vmconsole.git;a=blob;f=README

Please open an RFE for this. Thanks.

I think you can do that yourself, by editing:

/etc/ovirt-vmconsole/ovirt-vmconsole-proxy/conf.d/20-ovirt-vmconsole-proxy-helper.conf

It was recently mentioned [1] here that in 3.6, you can't start the
vm when you are in maintenance. Was this changed? Adding also Martin.

Are both on the same LAN? If so, you can just add the other as an additional
host, migrate the VM to it, then remove the first from the engine (after moving
it to maintenance). IIRC HA will forget about it after a week or so (in the
output of 'hosted-engine --vm-status'). In principle you can remove it manually
using 'hosted-engine --clean-metadata --host-id=1'. See also:

https://www.ovirt.org/documentation/how-to/hosted-engine/

If on different LANs, you can try using backup/restore:
