XOA 5.112.1 and 5.111.1 is fine [image: 1763748852814-7a8824a6-c2d2-4f78-8dda-8eb2a48f70e7-image.png] If I import a new ISO in 53c1a it show the correct name in both 53c1a and d3402

Looks very promising! Just a question, what does the customer care about what pool, host or SR the VM is deployed to? I mean that's normally nothing you get to choose at the other cloud providers i've tried. Or is that something only available to "resellers" who might have to balance their customers?

@dinhngtu Thanks for suggestions. I'm really delving into areas I haven't delved into before so thanks for help. I'm going to include a few screen shots here as I think this is the best way to show what's going on. I'm not sure if you've ever used ZFSBootMenu but there isn't any grub involved, but I understand what you're saying about the kernel command line parameters. So I after some testing - I want to confirm the serial method does work. To get serial console, ssh into DOM0: xl vm-list ---> To get <ID number> xl console -t serial <ID number> ***I'm not certain if this has anything to do with xcp-ng at all. Learning more about the issue and how zfsbootmenu works -- it's more a wrapper for kexec. ZFSBootMenu does allow for a chroot and from there you can issue a command line. Anyway I booted into the recovery console and typed the following: kexec -l /boot/vmlinuz-linux-lts --initrd=/boot/initramfs-linux-lts.img --command-line="zfs=tank/sys/arch/ROOT/default loglevel=7 rw console=ttyS0 earlyprintk=serial,ttys0" kexec -e Unfortunately probably beyond this forum, I ended up getting a kernel panic: Invalid physical address chosen! Physical KASLR disabled: no suitable memory region!

I guess it's my probably to fix at this point. What's wierd is if I delete the efibootmgr entry for the zfsbootmenu and then attempt booting using systemd-boot, the system will boot.

@bvitnik rhaaaaaa need. will have to dev this.

@nuentes said in Booting to Dracut (I trusted ChatGPT): Other things that I didn't mention yet that may or may not be relevent: the enclosure is connected with a USB-C cable to a USB-C input the enclosure hosts 4 disks Other disks/enclosures were not experiencing the disconnect issue The enclosure was actually working fine until a few days after I troubleshot/resolved an issue with one disk having slow transfer speeds. I switched the enclosure from USB-A to USB-C and also disabled spindown for the affected disk in the enclosure. Disabling spindown was done at the VM level, so I didn't mention it above. there is your problem USB is very unreliable for any kind of serious data transfer. Disconnecting devices, data transfer errors, corruptions are just the tip of the iceberg. For anything reliable you have to go for network attached storage or eSATA. I'm that type of a person that verifies md5 sums of all files copied to the USB flash, disk, enclosure etc. I've spotted data corruptions sooooo many times regardless of the OS, version, HW, USB type, storage device type... The only common thing was USB. eSATA and ethernet never produced such corruptions. As far as I'm concerned, USB is for mice and keyboards... and maybe a lamp or fan

@olivierlambert I'd like to see replicated vms in netbox, perhaps not syncing their IP address to avoid conflict DR VM as well

I haven't had too much difficulty hitting the esc key in time to get into the EFI config. Click the start VM button, quickly click away from the display area and click in the display area, then toggle the esc key until I see it take effect. I know I have a couple running at 1920x1080, but that's actually kind of a pain. I only did that to try and get a larger RDP window, RDP may be limited by the original "monitor" resolution, but this might also be fixed in later updates. This one VM has been up for a few years. (edit, yes this has been changed, VMs with a 4x3 monitor now RDP is whatever I have set).

Hi, I was about to suggest to use backup health check but it seems you'd like to avoid it In this case, I don't really have an answer, maybe @Bastien-Nollet or @florent does.

[edit] I just realized this was from 2024. So far I only have 1 of my 2022 servers changed to the XCP-ng drivers and management agent, the only thing that happened was the NIC went back to DHCP and a short struggle to shift it back to static. I use the e1000 profile when I set up a VM. This was previously using the Xen 9.4.x drivers downloaded from Xenserver. The only other glitch is that if you migrate the VM to another host in the pool, the management agent is no longer detected. But additional migrations and rolling pool updates and reboots are not bothered by this. I'm told this will be fixed in the next version. As far as the drivers themselves, I don't see any issues on this one VM. I think I have another 2022 in my lab with the XCP-ng stuff installed, I'll have to check later. I've had no issues with it. These were both installed from the new Tools ISO that is default with the latest XCP-ng 8.3.x

@Forza I keep hoping to see an Alpha or Beta of XCP-ng 9 soon, but I think there is still a lot of work to be done on the host side and on the Xen Orchestra 6 side.

@k11maris Same on my side. Delta backup for all VMs show this message. [image: 1763710321097-bildschirmfoto-2025-11-21-um-08.30.44.png]
