This is fantastic news! Thanks for sharing it. Olivier mentioned that something might be in the works but didn't mention much more than that.
I've used DRBD on various projects in the past and been nothing but impressed by it. It would be interesting to see if you could reach out to the folks behind HA-Lizard as well; they've got a lot of experience with DRBD on Xen systems.
@stormi So far, so good for my systems with the re-updated kernel.
@stormi No regressions so far on my test pool with both sets of test updates installed.
@stormi Updated my 8.0 test server and all seems to be working just fine so far.
@stormi Yup, I did just before trying to install the test update so I must have gotten it after you published. Everything seems to be working fine here afterward.
@stormi Running well for me. I've tested startup, shutdown, and migration of Windows and Linux VMs with no obvious regressions.
@stormi
I'll use this one to test the 8.2-to-8.2 upgrade we talked about on the software RAID thread.

Yes, that's how I found it as well. It's still not up on their blog as of this morning. I wonder if that's intentional.
It looks like Citrix has released their latest CU version (CU 1) for Citrix Hypervisor 8.2. No announcement yet on their blog about it but it's available for download as of now. Looks like it's mostly a patch roll-up though they indicate there are other fixes as well.

You're very welcome. My solution to the similar problem I'd had was to set up a couple of internal systems as NTP servers so that I always had something with the right time and static IP addresses and pointed everything needing NTP at them.
I ran into something like this once. I noticed you've got NTP set to use host names. You could see if it's maybe DNS lookups being slow to respond at that point in the boot by setting NTP to use IP addresses instead and seeing if that's much faster or not.
So much for my memory.....
XCP-ng center always exports a snapshot as a template. The menu item is called that and the xva files made always re-import as templates. The equivalent xe function is xe snapshot-export-to-template which does the same thing. The only way to export the snapshot as a VM is to set the is-a-template parameter to false then export with xe vm-export. Once that's been done it looks impossible to set is-a-template back to true. Using either xe vm-param-set or xe snapshot-param-set and trying to set is-a-template back to true gives an error "VM_IS_SNAPSHOT"
I remember one of the backup scripts, NAUBackup/VMBackup if you're familiar with it, doing this and was never quite sure why until now. Looking through its code, it's creating a snapshot, setting is-a-template to false, exporting it as a VM, then deleting the snapshot in order to make an xva file backup while keeping the VM live. I'm not familiar with backups made by XO but I'm guessing you must be doing them in a similar fashion.
Edit: I just did some more testing and discovered that as soon as I set the is-a-template parameter to false on a snapshot made by XCP-ng Center or xe vm-snapshot, it starts showing up in the xsconsole "All VMs" list and in xe vm-list commands just as snapshots created by XO do. In addition, they're showing up both on xe vm-list and xe snapshot-list. Fresh snapshots made with is-a-template still set to true show up in xe snapshot-list but do not show up in xe vm-list or xe template-list. They do show up in the list of templates available in XCP-ng Center when creating a new VM but those with is-a-template set to false do not.
This is starting to smell to me more like a bug in xe or XAPI and possibly XCP-ng center as well but definitely in xe or XAPI. Is there any way to look into what's going on there?
