    • RE: Unable to enable HA on a XCP-ng 8.2.1 Compute Pool

      @tjkreidl which host? Enabling HA on other pools doesn't trigger any host reboot.
      Enabling HA on this pool results in "Internal_Error(Not_found)"
      I am aware that a host reboots when you remove it from a compute pool but that is something separate.

      @tjkreidl ntp is synchronized across all the hosts. All the hosts can reach each other and are in a pool already. There are even vms running properly on the said compute. The only thing not working is enabling HA.

      @olivierlambert Yes. xe vm-list shows all the running vms on the pool

      @olivierlambert Notable error on that compute is that it can't find the UUID of the pool master, for some reason.

      172.21.17.96 is the management IP of the pool master(compute-01) while 172.21.18.96 is the IP for the same host, used as a Storage interface.

    • RE: Unable to enable HA on a XCP-ng 8.2.1 Compute Pool

      @olivierlambert The pool is showing all hosts as connected, same for all the shared SRs. There are even vms running on the new compute host. Only thing not working is enabling HA.
      One of the SRs is showing that HA is configured. Should that be the case when HA is not enabled yet?

      @olivierlambert I added a compute to the pool. It added successfully but HA won't come up.

      @Denson I also have a shared NFS SR already configured on the pool.

    • Unable to enable HA on a XCP-ng 8.2.1 Compute Pool

      Hi everyone,
      I've encountered an issue i've never seen before where trying to enable HA on a compute pool fails with the error "INTERNAL_ERROR(Not_found). NTP is enabled on all the computes and all the computes are already in a pool. I have updated all the hosts in the pool, just to rule out a pending update but no change.
      Below is the log output from the xensource log file from the poolmaster.

    • Installation of XCP Guest tool frivers on RHEL9

      Hello,
      Are the XCP Guest tool drivers supported on RHEL 9? I am having a challenge getting them installed. Installation of the guest tools provided by XCP-ng completes but the drivers are still shown as not configured. I have tried on several vms running RHEL9 and all behave the same. Hypervisor version is XCP-ng 8.2.1

    • RE: XCP 8.2 ssd error

      @olivierlambert Had the same issue with a similar server. Replaced both RAM and disk but the host kept going into read-only mode. The host would run just fine when installing any other OS/hypervisor. The server model is Supermicro SYS-6028TP-HC0R

    • RE: XCP-NG Host stuck in read-only mode

      @dmjorge This was never resolved. Replaced RAM and SSD, disabled SAS controller and same issue. Tried installing XCP on a different server but the same model and the issue re-occured.

      Installed Proxmox and it has been running without any issue. I believe there is a compatibility issue of XCP-ng and Supermicro SYS-6028TP-HC0R

      @olivierlambert This was resolved by editing the disk position. The disk position on XenServer was xvda and changing it to 0 resolved this.

    • Migrating VMs from Xenserver 6.5 to XCP-ng 8.2.1

      Hello all, looking for feedback as to a challenge I'm experiencing when migrating VMs from Xenserver 6.5 to XCP-ng 8.2.1. The exported vms fail to start and have the error "Boot device:Hard Disk - failure: could not read boot disk".The methods I have used to migrate are taking a snapshot of the VM,create a template from that snapshot, export that template to XCP then create a VM from it. The newly created VM will not start for some VMs. The only common trait that the VMs have is that they are Linux but they are diffrerent distros. I have tried removing xentools then trying the same but the issue still remains.

      Any insight or alternatives on how to move these VMs will be appreciated

      Issue still persisted after rebooting and running fsck. Host went into read-only mode not long after it came up.
