    Yes, and then Xen will reduce the RAM if there's not enough available to boot a new VM (reducing down to dynamic min). Static means it can't be changed live, while dynamic can.

    Migrating from XCP-ng Windows guest tools to Citrix

    I did it that way so as to get the old Citrix driver first, and then let it update and watch it reboot. That was my logic anyway. @dinhngtu said in Migrating from XCP-ng Windows guest tools to Citrix: @bberndt Okay, I managed to reproduce your situation. I think it's because the "driver via Windows Update" option was enabled after installing the XS drivers, which caused the drivers to lock onto the non-C000 device and prevent updates from coming in. Normally, XenClean should be able to fix the situation. But if you want to fix things manually, or if things still don't work (C000 is still not active), here's a procedure that should fix the problem: Take a snapshot/backup/etc. Keep a note of static IP addresses (if you have any; there's a chance those will be lost). You can also use our script here: https://github.com/xcp-ng/win-pv-drivers/blob/xcp-ng-9.1/XenDriverUtils/Copy-XenVifSettings.ps1 Reboot in safe mode and disable the non-C000 device. Reboot back to normal mode; it'll ask you to reboot a few more times. The C000 device should now be active and you should be able to get driver updates again. (Optional) You can now enable and manually update the non-C000 device (Browse my computer - Let me pick).

    Do you have any SR using a VM? (like an ISO SR in a NFS share inside a VM). This is freezing NFS and makes host taking half an hour to restart. Logs should tell you why the RPU failed if it failed

    It's impossible to answer right off the bat without knowing more in details what's going on. HA is a complex beast, and combined with HCI, requires a lot of knowledge to find what's causing your issue, between both xha and XOSTOR. In other words, it is very demanding to analyze all the logs and trying to make sense of it. However, I can give you some clues to make sense of it: The HA log is at /var/log/xha.log. When you shutdown a host, you should be able to watch (on each host) what the HA is deciding to do. My gut feeling: there's maybe a XOSTOR issue making the heartbeat SR being unavailable, and so all hosts will autofence Then you need to understand the XOSTOR logs for why the cluster wasn't doing what's expected. My best advice: remove HA first, and only then investigate on XOSTOR. Kill on node (not the master) and check if your VMs are still able to start/snapshot/write inside.

    PXE Boot from new VM not working

    @JBlessing as it looks like it does start, it looks like the networking side is working, at least at first. Just for debugging purpose you could try to switch that VM to BIOS instead of UEFI if it is possible, maybe it is related to what the pxe is starting in the VM. You could also try switching the VM between realtek and e1000 NIC, at this stage, PV drivers are not there so it is using an emulated NIC, maybe the image your PXE starts doesn't like the one you're using and it gets stuck somehow. As you're already using it with vmware, I assume you know how to size your VM, but if you went for a tight RAM value for this VM, you could try to give it more RAM to see if that could be related, as everything has to fit in RAM at some point, we may be using more at startup than vmware… Hope one of this can help

    About the xsconsole: sometimes it's not refreshing. You can try to get access to the console, then type "xsconsole" it will start it and you should see it works You must have the master up to date if you want your slave to connect again. I never tried to elect a new master in the middle of the upgrade, I would discourage it. Better shutdown some VMs on the master, upgrade it and you are automatically back on track.

    @Danp yes I ran "yum update" to be sure but "nothing to upgrade" on the pool-master. I try with storage (iscsi) NIC configured and without Storage NIC configured but the pool join freeze. Seems that persist some "SESSION" (may be referred to the slave host previously configured?) or some incoerence in the pool database... from /var/log/xensource of the slave host when try to join the pool: "session_check D:520c5b4e5b36 failed with exception Server_error(SESSION_INVALID, "

    @olivierlambert Agreed. The Citrix forum used to be very active, but especially since Citrix was taken over, https://community.citrix.com has had way less activity, sadly. It's still gratifying that a lot of the functionality still is common to both platforms, although as XCP-ng evolves, there will be continually less commonality.

    For anything older than the branches still shown in https://pkgs.alpinelinux.org, (from v3.0 to v3.12), the packages should be downloaded from their cdn: https://dl-cdn.alpinelinux.org/alpine But as mentioned above, anything older than 3 releases from the lastest current one(v3.21) are end of life and should not be used for more than testing.

    I already suggested you the solution, now it's up to you to live with those process or to decide to reboot (ideally after doing updates because it's very dangerous to NOT being up to date)

    Citrix tools after version 9.0 removed quiesced snapshot

    @vkeven XCP-ng 8.1 release note says VSS and quiesced snapshots support is removed, because it never worked correctly and caused more harm than good. Note that Windows guest tools version 9 (the default for recent versions of Windows if you install Citrix drivers) already removed VSS support, even for older versions of CH / XCP-ng I am not sure if this VSS feature is bound to the PV drivers, or if it also needs hypervisor support. Though it is not recommended to stay on a old version of the guest agent.
