When you boot in UEFI mode, press "e" to edit the boot command line, you have a line to change the memory for dom0.

How about doing your own matrix?

@dvdhngs install onto (mdadm/ZFS) RAID 10: no to use (mdadm/ZFS) RAID 10 as SR: yes, of course!

P.S.: I gave my latest "trick" another run: Did a full copy of the VM within xo to the other host. While that job ran, I started the delta backup that finished OK. After the copy was done I deleted the copy and saw - as last time - that the host was coalescing. After finishing the sr's advanced tab is empty again and stayed empty.

@danp said in XCP-ng 7.5.0 final is here: @dblogic said in XCP-ng 7.5.0 final is here: Just tried updating our pool and after updating the master had failed migration of VM (Ubuntu) and then was unable to get VM to start (Missing VDI error). Only solution was to roll master back to 7.4 and everything working again. I ran into a similar situation when I upgraded to 7.5 this week. Did you check to see if there was a non-existent ISO mounted in the CD rom for the VM in question? Thank you. That was my problem. I gave cd empty. Everything works.

Actually, looks like I had already written something about it in the Updates Howto: https://github.com/xcp-ng/xcp/wiki/Updates-Howto#a-special-word-about-xcp-ng-75-76-and-live-migrations

We have been using CR at work for over a year now and it is working great. There is no point of using the DR-feature since it is way slower and doesnt support incremental backups.

anyone can request a change in https://github.com/xcp-ng/xenadmin/issues

@stormi dd stands for disk dump and does exactly that: Copy a stream of data. Fio however can be configured for precise workloads and read/write mixes, parallel workloads etc. So the first thing will only give you streamline benchmarks, what almost nobody cares about. The second can simulate realworld (VM/database...) workloads, where (controller) Caches and non magnetic storage (Flash, Optane, MRAM...) makes the real difference. Also use big amount of data, since caches can impact small ones extremely. Don't get me wrong: We need them and they can make huge differences, but as long as your benchmarks fully fit into them, it gives your nonsense/fake results. Also (consumer) SSDs start throttling after some 10 to a very few 100 GB of data written. Their caches fill up and they 'overheat'. You can spend days on benchmarks and how to do what.

I tested on a fresh 2016 install. The install went well and the management agent was installed. I enabled VSS but the VSS snapshots don't seem to be working. To compare I installed the citrix client tools on a fresh 2016 install and VSS does work.

Thanks for your input! I think it might be the one then Also, if there is a big problem with it, we can always update the package!

Should I still just get a different NIC card?

Here's another willing script tester

Hello dear RC testers! We are releasing 7.5.0 final today, so here's how to go from 7.5.0RC to 7.5.0. Warning: this is only for people who installed the RC. Detailed procedure will be given in the release announcement for upgrading an XCP-ng 7.4 server Option 1, upgrade using the installation ISO Will work, although may be a little overkill since you already have a nearly-final 7.5.0. Option 2, update yum repository files and update the system # remove the RC-specific repository file if present rm /etc/yum.repos.d/xcp-ng-7.5.repo -f # install the 7.5 official repository file wget https://updates.xcp-ng.org/7/xcp-ng-7.5.repo -O /etc/yum.repos.d/xcp-ng.repo # update. If you had updated your RC regularly, this will install nothing, else you'll get a few packages yum update # if the kernel or xen-* packages got updated, reboot your server # that's it, you've got 7.5.0 final!

The case is solved. Here is an updated entry in our Troubleshooting Guide: Cause a) There can be leftovers from old Citrix XenServer Client Tools. -> https://github.com/xcp-ng/xcp/wiki/Troubleshooting#the-management-agent-installer-was-executed-but-the-pv-drivers-are-not-installed-in-the-device-manager

There's no "community" version of XOA, there's only Xen Orchestra Are you sure you are on master? Have you tried with XOA?

@kcah427 Thanks for sharing your solution. I end up using a Raspberry Pi as a Socat host and passing the USB Zigbee stick over ethernet to the VM. Not ideal but it works.

Hmm okay so it's not written directly. We'll see soon enough
