      @maxcuttins You can always have LVM SR on that RBD image device. You need to whitelist /dev/rbd in lvm.conf though.

      I'll test once XCP-NG 8 is available.

        Can you write few lines on how you did the initial steps? (so we can provide a SMAPIv3 driver for further testing)

        Oh yess!
        In reality I already wrote yesterday in the wiki everything we know as today about integration with CEPH:
        https://github.com/xcp-ng/xcp/wiki/Ceph-on-XCP-ng-7.5-or-later

        But this was before my test on XenServer8.
        However the steps are exactly the same.
        I summarize here the steps (but they are explained better in the wiki):

        yum install epel-release -y --enablerepo=extras
yum install centos-release-ceph-nautilus --enablerepo=extras
yum install yum-plugin-priorities --enablerepo=base
yum install ceph-common --enablerepo='base,extras,epel'

        And that's all.
        Since today we always needed to install other connector in order to use rbd.
        This mean no need for rbd-fuse (rbd over fuse), rbd-nbd (rbd over NBD), ceph-fuse (cephFS over Fuse). We can use the original rbd directly with kernel support.

        To map an image:

        Before you can connect you need then to just exchange keyrings in order to allow the client to connect.
        In order to connect to an image called mytestimage created on the pool XCP-Test-Pool.
        Map the block device:

        rbd map mytestimage --name client.admin -p XCP-Test-Pool

        Create the filesystem that you prefer on top:

        mkfs.ext4 -m0 /dev/rbd/XCP-Test-Pool/mytestimage

        And mount:

        mkdir /mnt-test-ceph
mount /dev/rbd/XCP-Test-Pool/mytestimage  /mnt-test-ceph

        I'm gonna to write down all these passages in the WIKI as soon as XCP-8 is out.
        Now the hype for the next release is even more. 😍
        I'm gonna to stalking @stormi all days 😈

          I throw down one of my xcp-host to setup a not-nested-virtualized xen-8 in order to test RBD speed. Performance are about 4x slower than they should be but at least it run almost like a standard local disk.

          dd if=/dev/zero of=./test.img bs=1G count=1 oflag=dsync
1+0 records in
1+0 records out

            Have anybody tried xcp 8.0 with the intel x56xx series cpu?

            why is support for this cpus dropped, are there any technical behind it or just that they are old and considerd Legacy?

            i would like to know if this cpus have been tried with this veriosn of xcp.

              1G is usually a really bad test, as pretty small things can influence the result massively.
              You should run tests with 10 or better 100 - if you can.
              That also diminishes influence of any caches (on source and target!).

                @Prilly XCP-ng 8.0 (the Host) is not released (even not an alpha or beta), I only released XCP-ng Center 8.0 (the Windows Client)

                  @Prilly the same thing I'm wondering what could be wrong with that cpus beside of high power consumption which is obvious becouse those cpus are about 7 yrs old.

                  VmWare is working with that cpu but 6.7 installer says that the support for that cpu will be dropped. And that would be not good for me becouse I would need to replace all of my servers which is not the case.

                    I hope XCP-ng will support legacy CPUs as I have E5-24XX series servers 😞
                    I guess they will work fine but as they are not supported officially ...

                    E5 arent legacy. Xeons x5xx are.

                      According to the XS HCL Citrix Hypervisor 8.0 is supporting Dell R420 servers but not Dell R430 (same model, but newer, you can still buy the R430). The newer R440 is also supported. This seems very odd to me. Has anyone any idea why this is the case?

                        While you're waiting for XCP-ng 8.0 beta, what about testing the latest security update to help us release it fast?

                        Thanks!

                          Been running CH 8.0 for a week to test it out. There's an issue with the guest tools. performance is slow because the guests I/O isn't "optimized"

                          going to revert back to xcp 7.6 today.

                                Guest tools on Windows (I suppose) aren't working well?

                                    Have you used Citrix tools directly from CH ISO or something else?

                                      yes, I used the ones in the ISO and through the system. I also tried some older ones.. In the end the system never recognized that I had the proper ones installed. Tried with 2 different windows VMs. Server 2016 and Win10
