    @jim.mcnamara Yes, master is really the host that controls all of this stuff, so you would need to run the command on a host running as master. Each host defaults to be its own master, but when you join one to a pool it will "demote" itself from that role.

    @gduperrey Thank you for the reply. The use case is to centralize all of our reporting and monitoring for all of our devices. We have a number of XCP host, various servers, etc, that we are responsible for, and all of them besides our XCP nodes are being monitored for real-time analytics by Netdata. We are also using Zabbix for trending and long term usage but would like to be able to move the XCP nodes into our Netdata cloud versus being just on XOA/XCP. I also understand this would be overidden by updates and that you guys cant support it. I mainly wanted to see if it would "break" anything you already have in place. As a feature request, maybe have a way that you can report to a Netdata cloud instance. That would be nice.

    Hello, @nikade Yeah i think like this already, but i'm surprised by the result of the calcul. I should i have either: 3 nodes which can die, or "1", but i should not have the same number right ? in my case, i run the command in a 3 hosts cluster and it return me 3 as value. which disturb me. Best regards,

    Hi, Yes, by default, adding a new host to a pool, it will be lowered on CPU features to the common denominator, in other word, cutting that's not common between all pool members. So: If you add a more recent CPU to an existing pool, the CPU won't use new CPU features If you add an older host to a pool, it will lower down all features from existing CPUs

    @Niall-Con Thank you! I'll take a look to that and will ping you to test on real hardware. Just need to find time (in the middle of storm right now), so it'll take one or two weeks most probably.

    @kagbasi-ngc said in VM Console Screen Suddenly Inaccessible: Hmm, interesting observation about potentially this being a failed migration issue. I can confirm that none of my users in the lab are migrating any VMs or this particular one, for that matter. However, I do have the Load Balancer plugin running and it could be the source of a migration that could've failed. How can I confirm this in the logs? I mean, what should I be looking for? While trying to find logs, you can try to find the VM in question and see if it is using local storage rather than shared.

    Don't worry, glad you asked to avoid having bigger problems later edit: there's a Python SDK for XAPI if you need.

    @flakpyro From my experience, VM with UEFI boots faster than BIOS. For some OS versions UEFI runs faster IF there are no Xen drivers. But for most installs it does not matter much, except for Debian... which has given me problems with pool/migration/reboot with the UEFI installs on XCP (there's a workaround). So, I would vote for UEFI as the default for all OS/VMs that support it correctly since most are moving to that anyway (including XCP hosts).

    @dinhngtu Thanks for your help. I solved to install XS Tools uninstalling old XS version 9.0, running XenClean and installing version 9.4. Also Disk stats now are correct. Now I get these good performances: [image: 1747727185969-a6beabc3-793e-41d7-9f03-4689db372275-immagine.png] [image: 1747727202526-20d58e2a-e9f9-4d7b-ba44-844dca2008fa-immagine.png]

    @plaidypus You can configure the disk within the guest OS to match whatever formatting you want. I would suspect the performance gains would be included as well, but you'd have to test and verify.

    @sborrill And for completeness, try pvshim (a.k.a. pv-in-pvh) using xl: Download https://ftp.netbsd.org/pub/NetBSD/NetBSD-10.1/amd64/binary/kernel/netbsd-INSTALL_XEN3_DOMU.gz Create /root/nbpv containing: name = "nbpv" type="pvh" pvshim=1 pvshim_cmdline="pv-shim console=xen pv-linear-pt=true" kernel = "/root/netbsd-INSTALL_XEN3_DOMU.gz" memory = 1024 Boot VM successfully with xl create -c nbpv So pv-in-pvh does work (does require pv-linear-pt=true on shim command line though).
