I have one CentOS7 host (physical) & 3x oVirt nodes 4.1.2 (these are vm's).
I have installed vdsm-hook-nestedvm on the host.

Should I install vdsm-hook-macspoof on the 3x node vm's?


Hello,

You should install macspoof hook on the host you're using for
virtualization, not on the guests.

Re: [ovirt-users] Building oVirt engine on Debian

[Leni Kadali Mutungi]

I have read what is in the README.adoc and done all of it.
Unfortunately, even with BUILD_ALL_USER_AGENTS=0, my computer would
still freeze. I had to opt to not build the gwt ui instead. I hope
it's not too important :P.

Build went on fine. Ran into this issue:

install: cannot create regular file
'/usr/local/etc/logrotate.d/ovirt-engine-setup': Permission denied
install: cannot create regular file
'/usr/local/etc/logrotate.d/ovirt-engine-notifier': Permission denied
install: cannot create regular file

make[1]: Leaving directory '/home/user/ovirt-engine'
Makefile:521: recipe for target 'install-dev' failed
make: *** [install-dev] Error 2

So usually I'd solve this by running as root, but since you've advised
against it, what should I do to give the normal user permission to run
this operation since the folder is owned by root and the group is
staff? My looking through other responses to similar situations
indicates to me that giving the non-root user access to this folder
isn't recommended. What would be the best solution in my case?

Re: [ovirt-users] Network interface not working

[Lev Veyde]

Hi Alex,

That is quite strange...

Does this happen on both hosts - have you tried to migrate the VM to the
second host and see if the issue still remains?

Thanks in advance,

Hi Lev.


On one of the VMs you only see 1 NIC instead of the 2?

NO. both VM's sees two NIC, but on first VM ping with no error, and 
second VM ping with 75% error.

Hi Alexander,

So if I understand it correctly, you have the following configuration:
- 2 hosts, each having 2 NICs
- 2 virtual machines, each have a connection to each one of the NICs
available on the hosts

On one of the VMs you only see 1 NIC instead of the 2?

Are you sure that the VM is properly configured to have 2 NICs?

What Linux distro and version you're using on the hosts and inside the VMs ?

Can you please send us:
- the logs from the VM, e.g. /var/log/messages
- the output of lspci -v
- the output of ip link

Thanks in advance,
