    perhaps "in the context of a proceeding RPU, do not start halted VMs" ? or "boot only halted VMs that have HA enabled" ? but I can imagine corner cases where this is not wanted. some chicken & egg problem.

    @CyaVMware said: Have a simple question for someone. Looking at migrating a client to XCP. Currently they have a data disk that is exactly 2TB in VMware. My question is the limitation anything OVER 2TB, or is it 2TB AND above? I'd prefer not to use the VMware converter tool to shrink the disk to 1.99TB if I don't have to. VHD format has a strict limit of roughly 2TB (around 2040 GB), so if your client’s VM disks are larger than this then you’re going to have trouble with VHD format. However QCOW2 support is almost here (production ready) about to reach RC2 state, once this reaches stable you’ll be able to safely reach a max of around 16TB. That is if your using ext4 based SR, other Filesystems have different limits. If using a networked file sharing protocol service then, the limit of the host server’s filesystem applies. Though QCOW2 VDI has a limit of 16 TiB.

    We are now live again with all the VMs - which is a relief. The above steps from @stormi were great, the one thing I notced was the /etc/stunnel/certs directory didn't exist. I created that manually and everything else seemed happy. I did have to mess about a bit with the fibre NICs, but I've repeated the previous renaming and that's now running fine. Thanks very much for all the help - I appreciate it.

    There is some diff, but not that much between HyperV, ESXi and Xen. However, it's big enough to require a lot of effort to get nested working correctly, one small mistake and your VM is dead.

    @randyrue Confirmed that after cold booting a VM to a new host I can then migrate it live to another new host.

    I believe Proxmox Backup Server kernel Linux pbs 6.8.4-2-pve has also the same issue. updating to Linux pbs 6.8.12-1-pve solves.

    @darkbounce Short answer: it seems that Intel hybrid architecture is finding a way to make something that would result of Xen running the VM with the less "featured" CPU, meaning your VM will never use all P core instructions that aren't on E core, meaning... it will work without disabling one or another. Hard to tell how much is lost in terms of perfs vs the best Intel hybrid scheduler (which is on... Windows) but probably not that much on a machine with a reduced number of P cores like this one.

    @yammy I hope you are not talking of installing Docker in the Dom0, because this is really a bad idea.

    @PontusB i don't even know if disabling option 66 solves the issue but as soon as we add option 66 in our DHCP server it boots fine from XenServer (but without HA between the many PVS servers).

    @bloodyskullz If you still see the old ISO SR, the easiest way to migrate is simply by creating a new one and migrate the ISOs through XO to the new one. In regards to deletion of the old SR you need to check if it really is mapped to another drive or if the mapping was not working and it filled / if so, you might not be able to delete it

    @bleader said in update via yum or via xoa?: yes you're basically doing an RPU manually. But it is indeed odd that the process is stuck at 0%, it should be fairly fast to do the install patches, no errors in the logs? i've another install all patches and install all. Now i'll use rpm update and see if speed is the same or not

    Pool Tasks Don't Complete? Major Issues...

    @Danp Yes to both. I've probably restarted the toolstack at least a dozen times, mostly to clear hung tasks. I did notice some weird issues with a secondary SR being disconnected on xcp02, (one of 10 hosts, 9 after I ejected and forgot xcp01), but there's no disks on it. It wasn't being used for anything at all (yet), and it's fine on all the rest. That does lead me to think maybe it was a power bump that rebooted a switch or something though. Maybe it caused some kind of hangup with xcp01 and xcp02, and since xcp01 was the pool master, it cascaded to the other issues I've seen? Could that cause the VM's that were originally running on xcp02 to die and not be able to be recovered easily?

    No, from the XCP-ng point of view, the VM is still running without any interruption.
