    No. I'm saying that all VMs (HVM) are using RFB consoles, readable with VNC protocol (used by XO or a VNC client). There's no text console since it's like a screen in HVM. If you are stuck on "Loading in progress", it's not a console issue, it's a VM issue. You can use a LiveCD to check what's going on.

    Hi I already know that upgrading from XenServer 8.2 to XCP-ng works .. tried it on a test machine seems to work fine except for SRs (they don't seem to work correctly) I'm wondering if it would be any better by doing a clean installation vs an upgrade ? Would there be any difference .. In particular I'm thinking about the partitioning of the disk. I know that going to Xenserver 8 from my current XenServer 8.2 (which came from 7.0) has issues with the partitions and cannot do the rolling pool upgrade because of that . (based on Citrix pre-checks). I'm also wondering how XCP-ng handles this in the upgrade process .. and if XCP-ng can do this why can't Citrix to the same .. Is Citrix just being lame / lazy ? thanks

    @ph7 I don't see anything related to the dongle under PCI devices. When I plug in the stick I do see a new device named /dev/ttyACM0 in the host console.

    Upon further testing, it seems that initiating a rescan of the 0 byte SR fixes the size issue. However, I should not be having to do this but at least it appears to be more easily dealt with than I previously assessed.

    As a general rule, you MUST keep all your hosts up to date. If you update normally, you will be on a 8.2.1

    @Danp said in Patching and trying to Pool Hosts after they've been in production: Warm migration should work in this case because the VM is halted then restarted as part of the process. See here for more details. Sweet, I'll setup something small on the old host for testing and use the Warm Migration process.

    There's no issue to restore everything from scratch, as long as your backup repo (BR/remote) is available. For example, fresh XCP-ng install, deploy XO, connect to the BR and it will find all your previous backups. Then restore, that's it!

    Now we have 76 VMs running on a 3 host pool. Each server has 320 GB of RAM. Our scenario doesn't need big CPU resources so everything works fine.

    @wilsonqanda Yes, BIOS as well, assuming I am remembering right haha. If you just pick whatever is closest and go with it I doubt you'll run into issues, if you do just make a post here and I'm sure someone will be willing to help out or work on a new template or something.

    The grub setup is rather simple and not very flexible. There's just one file to modify, as you found out (/etc/grub.cfg in BIOS mode, /etc/grub-efi.cfg in EFI mode, both being symbolic links to the actual file location). You can add an entry to it, but there's a small chance this doesn't play well with scripts from either XenServer or ourselves which may want to update the file and get confused. It's usually better to just modify the existing entries, ideally using /opt/xensource/libexec/xen-cmdline, so that the file structure remains unchanged.

    You need a fully up to date XO (check that first). If you are on XOA Free, you might need a trial (send me a private chat message with your email registered to this XOA, so I can unlock you the free trial). Alternatively, you can also use XO from the sources

    Just updating for anyone that has the same issue, we ended up just rebooting the master and like @JamuelStarkey said everything just automatically fell in place. Did have to exit maintenance mode on the master and replug the PBD but everything else went back to normal immediately. Still frustrating to experience and would really love to know what caused this. If there's any logs I can pull to figure this out do let me know @olivierlambert

    So I managed to get the VM to see both drives. In dmesg I can see something like this [ 1.160149] ahci 0000:00:08.0: AHCI 0001.0301 32 slots 1 ports 6 Gbps 0x20 impl SATA mode [ 1.161043] ahci 0000:00:08.0: flags: 64bit ncq sntf ilck led clo only pmp fbs pio slum part [ 1.187888] ahci 0000:00:09.0: SSS flag set, parallel bus scan disabled [ 2.186211] ahci 0000:00:09.0: controller reset failed (0xffffffff) [ 2.187307] ahci: probe of 0000:00:09.0 failed with error -5 So I removed the pci and did a rescan with root@mars-test-uefi:~# echo "1" > /sys/bus/pci/devices/0000\:00\:09.0/remove root@mars-test-uefi:~# echo "1" > /sys/bus/pci/rescan Now when I checked dmesg it shows up properly [ 795.538214] ahci 0000:00:09.0: AHCI 0001.0301 32 slots 1 ports 6 Gbps 0x4 impl SATA mode [ 795.538219] ahci 0000:00:09.0: flags: 64bit ncq sntf ilck led clo only pmp fbs pio slum part fdisk -l also shows up both drives now too root@mars-test-uefi:~# fdisk -l Disk /dev/sda: 7.28 TiB, 8001563222016 bytes, 15628053168 sectors Disk model: ST8000DM004-2U91 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/sdb: 7.28 TiB, 8001563222016 bytes, 15628053168 sectors Disk model: WDC WD80EFZZ-68B Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes It seems like on boot it tries to find the device but it fails to, but on a remove/rescan it seems like its fine? The question now becomes, how do I make this work ON boot.
