  Great projects have great documentation. Is XCP-ng a great project?

  Recent changes to the documentation: Updated https://github.com/xcp-ng/xcp/wiki/Updates-Howto with a "Precautions" section, and a "Get information about the updates" section. Added https://github.com/xcp-ng/xcp/wiki/Additional-packages about additional packages installed to dom0, be it from XCP-ng repositories or from outside (CentOS, EPEL, and more).

  I did contribute on the RBDSR plugin (v1). Creating a LVMoRBD would be easy. The other good point using LVM over RBD is the native fsfreeze when doing snaps and co which is not the case with rbd snaps. VM has to be paused (which issues fsfreeze) before rbd snaps. But LVMoRBD would put all VM on 1 single RBD. Difficult to maintain regarding dev size. Best would be qemu-rbd. I did use it like 10 years ago over native xen and it did work fine (ensures fsfreeze etc). There were a tech preview using libvirt with xenserver. Didn't test if it works on upstream version 8.

  @araxy said in security breach MDS processor XEON: @olivierlambert said in security breach MDS processor XEON: hyper-threading Disabling hyper-threading is losing half the power of the server ... If people have access to VM but not root, is it good? Do You have logs for CPU usage? In my VM environment the CPU utilization is not exceeding 25% for all the time. IDK how it looks on Your site but if I would disable HT I think it wouldn't be even noticeably in a matter of performance of VM's.

  @olivierlambert I installed Citrix Hypervisor 8.0.0 as a VM. In the Host Performance Information: "CPU Usage" and "Memory Usage" are Unavailable like in XCP-ng 8.0.0 Pity! I couldn't check this information in VM submenu, because XOA installation failed (no hardware virtualization support (or similar wording) in the nested hypervisor).

  @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.

  @olivierlambert So I just created a new Win 10 VM and made sure to use the template. I created this VM in the XCP-NG XenCenter. I then went into XOA and "Windows Update Tools" is checked to the on position by default. This is what the problem I had earlier was. The VM defaults to grabbing the guest tools from the WU server. So if you boot up the 1st time with this configuration, it will grab the Citrix tools 1st and you can't install the community tools.

  @borzel Indeed, the command "xe vm-cd-eject --multiple" worked! All VMs now correctly auto boot on reboot/startup!

  @borzel In my humble opinion, I would say no because then you are deviating from industry standard naming. The reason for standards is so that everyone will know what you are talking about as long as you follow the standard. Lowercase b always means bit and uppercase B always means Byte. Please do not change this. It is trivial to learn the standard. It is less than trivial when people start making up their own abbreviations for things (though admittedly this one isn't rocket science to figure out).

  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.

  Xen is doing all the CPU and memory sharing, so Xen is a type 1. Network and storage are delegate to the privileged domain (dom0).

  @stormi Thanks for the links and I will start to dig in to them more to learn how it can be done. In a quick review of the links, this may be what I need since I do not think that I will actually need to re-compile XCP-ng, but just add for the setup of some additional installation steps via rpms and yum as well as some configurations at this point. This is really an experimental endeavor for the moment while it also allows me to learn more about the whole installation and setup of XCP-ng along the way.

  Hi All, In some of the latest read that I have been doing, it seems that the XenServer folks were also investigating the ideas of so called "Sub Domains" or "Driver Domains" via Mini-OS and MirageOS as minimal OS's to deaggregate Dom0 to take drivers out and make them independently sufficient such that if something happens to one of them then the rest of the system remains unaffected. This links into the ideas of Unikernels but I think that a lot of this is still in the R&D phase although some great ideas, to be sure. I could see a whole set of Sub-Domains to handle just about all of the functionality that Dom0 currently manages in perhaps a future evolution. Cheers

  That will be very exciting to see when it is ready since I think that it will help a lot of people.
