Engine deployment fails with engine booting to grub rescue
by Andy
After working through some DNS problems I was able to install oVirt 4.4.1.1 and progress the engine deployment stops within the ansible scripts. The system deploys the gluster domain, creates the engine, starts the engine, however it will never fully boot and complete the deployment. Bringing up the console of the engine sets it into rescue mode. I have attempted to set the appropriate variables in grub rescue
set root=(hd0,msdos1)
set prefix=(hd0,msdos1)/boot/grub
insmod normal And this will not boot the engine. Is there a procedure to mount a CENTOS 8 rescue CD/ISO to troubleshoot this or is there a specific fix published for this problem? The specific error I am seeing in the Engine Console is "attempt to read outside of HD0. I upgraded the ovirt engine appliance package to ovirt-engine-appliance-4.4-20200716090128.1.el8.x86_64 which produces the same result. I have gotten this error deploying on both my Intel and AMD based servers.
any help is appreciated.
thanks

VM Portal on a stand alone server
by gal.villaret＠gmail.com
Hi Folks,
I'm rather new to oVirt and loving it.

I would like to be able to run the VM Portal on a stand-alone server for security concerns.
Can anyone point in the right direction for achieving this?
Thanks,

ovirt-node-ng-image-update 4.4.1 to 4.4.1.1
by David M. Hornsby
All,
I applied the recent update 4.4.1 -> 4.4.1.1 to a host in a cluster and it failed. After reboot it was hund at the emergency console. I reinstalled 4.4.1 fresh on the host. Prior to adding it back to the cluster I applied the same update with the same result. Is this just a bad update or is the post install script bad.
Thanks,
David.

Andrea asked about hosted-engine, where you do not (by default) run restore

I think this is not a critical failure, and is not what failed the restore.

This is part of 'engine-setup' output, which 'hosted-engine' runs inside
the engine VM. If you can access the engine VM, you can try finding more
information in /var/log/ovirt-engine/setup/* there. Otherwise, the
hosted-engine deploy script might have managed to get a copy to
/var/log/ovirt-hosted-engine-setup/engine-logs*. Please check/share these.

Another option is to do the restore manually. To find relevant information,
search the net for "enginevm_before_engine_setup".

mixed hyperconverged?
by Philip Brown
I'm thinking of doing an SSD based hyperconverged setup (for 4.3), but am wondering about certain design issues.
seems like the optimal number is 3 nodes for the glusterfs.
but.. I want 5 host nodes, not 3
and I want the main storage for VMs to be separate iSCSI NAS boxes.
Is it possible to have 3 nodes be the hyperconverged stuff.. but then add in 2 "regular" nodes, that dont store anything and arent part of the cluster?
is it required to be part of the gluster cluster, to also be part of the ovirt cluster, if thats where the hosted-engine lives?
or can I just have the hosted engine be switchable between the 3 nodes, and the other 2 be VM-only hosts?
Any recommendations here?
I dont what 5 way replication going on. Nor do I want to have to pay for large SSDs on all my host nodes.
(Im planning to run them with the ovirt 3.4 node image)

using which client? remote-viewer? on which platform?
qxl needs drivers, not sure if Arch has that…it should have, but for Windows you definitely need to install them. If they’re not all right it falls back to vga emulation which is then slow indeed

What permission do I need to get API access
by miguel.garcia＠toshibagcs.com
We use LDAP authentication to login to ovirt cluster, actually, admin and another user account have to access API with no problem. My account does cannot access to API despite that had SuperUser privileges than those accounts that already access API.
Every time I tried to access API I get next message:
Error during SSO authentication access_denied: Cannot authenticate user 'diagsbuilder(a)ralntdom.rtptgcs.com':
No valid profile found in credentials..
The account does exist and permissions to enter to portal vms
What do need to do to grant access to API?
