The thing is that it works very well and doesn't need fixes…  I know, not usual right? It was so stable that we left it like that waiting for people coming for bugs and nothing happened… We'll cut a 1.0 in the next weeks/months.

I have indeed seen the stability of it myself. But the lack of updates made me worry anyway. But I'm really looking forward to the promotion to 1.0 as well.
Thanks!

The funny thing is, the asset that it reports as vulnerable is the VM that is running XOA (official image provided by XCP-NG). It is deployed recently, so everything is up-to-date, but even then I don't understand how it reports the XOA VM as the one containing the vulnerabilities.

(It might be fixable, because copying kernel and initrd to dom-0 and directly setting PV-kernel, PV-ramdisk and PV-args works, which is basically what pygrub is supposed to do. But I stopped investigating as pvhgrub is a much better option which acually works.)
You have 3 options

copy kernel and initrd do dom-0 and configure

xe vm-param-set uuid=... domain-type=pvh
xe vm-param-set uuid=... PV-kernel=/dom-0/path/to/kernel
xe vm-param-set uuid=... PV-ramdisk=/dom-0/path/to/initrd
xe vm-param-set uuid=... PV-args="root=... ro console=hvc0 ..."
xe vm-param-clear uuid=... param-name=PV-bootloader

Not a very practical option, just PoC.


use pvh-ovmf, but this requires UEFI-enabled VM (ie. GPT disk layout with EFI partition and some EFI bootloader or kernel directly in EFI with proper config (or as UKI)


use pvhgrub. You need a recent grub2 to build the image for i386-xen_pvh target. Or just get the blob - this one is from Alpine package


curl https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/grub-xenhost-2.12-r8.apk | tar -xzf - --strip-components=3 usr/lib/grub-xen/grub-i386-xen_pvh.bin

Save it to dom-0 (e.g. to /var/lib/xcp/guest/grub-i386-xen_pvh.bin) and configure the VM
xe vm-param-set uuid=... domain-type=pvh
xe vm-param-set uuid=... PV-kernel=/var/lib/xcp/guest/grub-i386-xen_pvh.bin
xe vm-param-clear uuid=... param-name=PV-ramdisk
xe vm-param-clear uuid=... param-name=PV-args
xe vm-param-clear uuid=... param-name=PV-bootloader

If the VM has valid grub2 config, it should work. Of course, you need a linux kernel with CONFIG_XEN_PVH enabled.

I absolutely understand the point regarding datacenters. I am using xcp-ng for years in smaller - non datacenter - environments and its great. Therefore I added the nut packages (8.2 and 8.3) and it works like a charm. It's installation is well explained in:
https://xcp-ng.org/forum/topic/4300/performing-automated-shutdown-during-a-power-failure-using-a-usb-ups-with-nut-xcp-ng-8-2/13?_=1742229073030
However, I agree with @Kajetan321 that it would be great if the nut package could be included in the standard "updated" packages repo since its added quite some benefits (imho) for "smaller" IT environments. However, I do not know how much effort it takes to maintain that.

@sapcode said in openssl 1.1.1 update or manual build in XCP 8.2.1 possible ?:

Would it be safe to run yum remove openssl as the first step or would this break the XCP installation:

The second option. And actually it's not openssl you're looking for, it's openssl-libs, and removing it will not even work, as it attempts to remove yum and systemd which depend on it and are protected.
Note that we do offer openssl 1.1.1 through the xs-openssl-libs package, and that is what XAPI uses for communication instead of the system one. However you'd have to patch and rebuild curl or wget so that they use it, and this definitely voids your warranty.
You are going on a journey that is far more difficult than you initially expected, I fear. So I'd start questioning the initial needs again.

Why do you need to contact websites such as ssl-tools.net from dom0?
Can't you do it from a VM?
