Hey, Debian folks! After updating to Buster, my system is unable to boot with the Xen hypervisor. When I try and boot, the screen gets stuck loading the ramdisk: > Loading Xen 4.11-amd64 … > Loading Linux 4.19.0.8-amd-64 … > Loading initial ramdisk …
I’m immediately suspicious of the version mismatch, especially since booting “Debian GNU/Linux” instead of “Debian GNU/Linux, with Xen hypervisor” works just fine. I still have the appropriate xen package installed: > bash# apt install xen-system > Reading package lists... Done > Building dependency tree > Reading state information... Done > Note, selecting 'xen-system-amd64' instead of 'xen-system' > xen-system-amd64 is already the newest version > (4.11.3+24-g14b62ab3e5-1~deb10u1). And there doesn’t seem to be a 4.11 hypervisor option: > bash# apt-cache search xen-hypervisor > xen-hypervisor-4.11-amd64 - Xen Hypervisor on AMD64 > xen-hypervisor-common - Xen Hypervisor - common files > xen-hypervisor-4.8-amd64 - Xen Hypervisor on AMD64 Furthermore, there also aren’t any packages for a 4.11 stock kernel to match the hypervisor: > bash# apt-cache search linux-image-4. | fgrep 'amd64 ' | egrep -v > 'headers|cloud|rt' > linux-image-4.19.0-8-amd64 - Linux 4.19 for 64-bit PCs (signed) > linux-image-4.19.0-6-amd64 - Linux 4.19 for 64-bit PCs (signed) > linux-image-4.9.0-11-amd64 - Linux 4.9 for 64-bit PCs > linux-image-4.9.0-12-amd64 - Linux 4.9 for 64-bit PCs > linux-image-4.9.0-4-amd64 - Linux 4.9 for 64-bit PCs > linux-image-4.9.0-8-amd64 - Linux 4.9 for 64-bit PCs > linux-image-4.9.0-9-amd64 - Linux 4.9 for 64-bit PCs (I also checked what old kernels I had lying around in /boot; only a few varieties of 4.9.0). Am I correctly understanding the issue here? If so, is there a way to get a newer xen hypervisor from a repo somewhere? (I can’t find it in backports or proposed-updates). Or, is there a way to find a matching old kernel image? And if not, where do I start debugging? Thanks for your help, - Garrett
