Description of problem:
Hi,

I have a very strange issue since oVirt was updated to 3.6.5.
When I start VMs with a specific VM name (auto-generated), oVirt returns the following error : 
"Exit message: Invalid machine name"

Version-Release number of selected component (if applicable):
oVirt 3.6.5

How reproducible:
For eg, create a VM with these names fails (from API or from web interface):
kitchen-fermewebovirt-role-webserver-jessie-c_1463043674.809774
kitchen-fermewebovirt-role-webserver-jessie-c_146304367.4809774
kitchen-fermewebovirt-role-webserver-jessie-c_14630436.74809774
kitchen-fermewebovirt-role-webserver-jessie-_1463043674.809774
kitchen-fermewebovirt-role-webserver-jessie-_14630436.74809774

But, these hostnames work:
kitchen-fermewebovirt-role-webserver-jessie-c_1463043.674809774
kitchen-fermewebovirt-role-webserver-jessie-c_1463043674809.774
kitchen-fermewebovirt-role-webserver-jessie-c_146304367480977.4
kitchen-fermewebovirt-role-webserver-jessie-_1463043.674809774
kitchen-fermewebovirt-role-webserver-jessie_1463043674.809774
kitchen-fermewebovirt-role-webserver-c_1463043674.809774


So strange...

related to bug 1291360. Please verify you have 1.2.17-13.el7_2.4 on hosts

There are more bugs which are still in progress, e.g. bug 1289363. I wouldn't use anything longer than 59 chars until things settle down. If you find an issue with 60-64 chars it may be that not-yet-fixed libvirt problem, please feel free to follow up there to see it's the same issue or not

Yes, it is the version I have:
libvirt-daemon-kvm-1.2.17-13.el7_2.4.x86_64
Comment 3 Michal Skrivanek 2016-05-13 08:07:40 UTC 
then please check if 59 chars long names work and if you have a testing setup you can also try if libvirt 1.3.4 would help(you may need to compile it yourself though, so not simple to try)

Yes, I am not able to reproduce the issue when length <= 59 chars.
I will reduce hostname length during generation into library I use (vagrant-ovirt3).

Thanks for your help.
