I ran this script to build XO on CentOS 7.
https://github.com/ronivay/XenOrchestraInstallerUpdater
It said it was successful.
systemctl says xo-server is active & running.
But when I go to it's IP address in my browser I don't get anything.
I can ping the IP address from the same PC that I'm trying to browse from.
What am I missing?

RE: Disaster Recovery backup auto-starting VMs (but shouldn't)
@olivierlambert
No, the 2 DR VMs that auto-started, don't have the blocked-operations set, the other DR VMs from other days do have it set. -
RE: Disaster Recovery backup auto-starting VMs (but shouldn't)
@olivierlambert
Well I just rebooted my secondary host again via iDrac & these DR VMs started up again.
Note, it started 2 of the same one. And I'm 110% sure I didn't force start any of these, just rebooted the host.

RE: Disaster Recovery backup auto-starting VMs (but shouldn't)
@fohdeesha
Thanks for the help everyone. I'm 100% sure I did not force start this VM. In fact all of the DR VMs were running. I know my screen shot it only shows 1 running, but I killed the others ASAP before taking the screen shot.
What I think happened is the secondary host crashed, so I rebooted it.
And I see this parameter is set: actions-after-crash ( RW): Restart.
Is it possible that when the host recovers from a crash it sends the signal to the VMs to force restart? I sent you the parameter of the DR VM that did start up date 2021-07-18 (above), but if I list the parameter from the DR VM for the next day 2021-07-19 the block parameter is set:[07:48 VULCAN ~]# xe vm-param-list uuid=e327b268-887d-395a-9665-2509c341df21 uuid ( RO) : e327b268-887d-395a-9665-2509c341df21 name-label ( RW): rivieraVM2 - Daily Disaster Recovery - (20210719T165550Z) name-description ( RW): Windows Server 2016 License Manager & Print Server user-version ( RW): 2 is-a-template ( RW): false is-default-template ( RW): false is-a-snapshot ( RO): false snapshot-of ( RO): <not in database> snapshots ( RO): snapshot-time ( RO): 19700101T00:00:00Z snapshot-info ( RO): disk-snapshot-type: crash_consistent;

Disaster Recovery backup auto-starting VMs (but shouldn't)
Hi, I have a Disaster Recovery backup set up to store the VMs on my secondary host. But whenever I re-start the secondary host, the VMs on it automatically start up, conflicting with the VMs that are already running on the primary host. How can I prevent this from happening?
-
RE: Will it Live Migrate...?
Thanks very much for the info. I think I'll go with option 1.
I have another question about the internal storage. My new server has (2) 1TB SSDs using XCP-NG's software RAID for the OS & VM internal storage. The old server has a Dell PERC hardware controller with (6) drives in RAID-5. Can I install XCP-NG & the VMs on this Virtual Disk & still be able to migrate them? -
Will it Live Migrate...?
OK my main XCP-NG/XOA server is on a Dell PowerEdge R640 with (2) Intel Xeon Silver 4110, 8 core CPUs. I also have an older 2013 Dell PowerEdge R620 with (2) Intel Xeon E5-2620, 6 core CPUs. If I install XCP-NG/XOA on this older box will I be able to live migrate my VMs to it as a backup host? I think I read somewhere that the CPUs need to be similar for the live migration to work. Are these similar enough?

RE: XOA Update patches fails
Oops, sorry. I had enabled the Centos-Base repo.
I've disabled it now & the 268 patches are gone now.
