Can I safely delete these orange disks?
I'm assuming they're leftover/orphaned disks, since the real ones are green on my other host.

@Pilow, Well, it was a major pain, but I got both hosts on eth0 for management & eth2 for Storage10g & it's working now.
I wish XOA made this an easier process.

@Pilow Do you mean both NICs need to have the same ID? e.g. both on eth2? How would I change that?

I get the following error when I try to migrate a VM to another host.
I'm selecting Storage10g as the migration network and both hosts have this network configured.

@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.

@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.

@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:

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?

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?

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?

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

Yes, DNS is configured correctly on my PIF

Says XOA is up-to-date

XCP-NG = v7.6.0

This is a fresh install is of 2 hours ago.

DNS is configured in iDRAC

My pool says it has 268 patches.
When I click Install all patches I get this error:

}

hmmm, I thought when I installed XCP-NG & it asked where to store the VMs it set the default SR...
But I just manually set it & it's working now thx.

I used the one line installer, set the IP & then got this....

I was able to fix my issue by adding http to firewalld.

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?
