Hi, I am Fulgurance, and I use actually daily Gentoo. Recently I choose to
reinstall all of my system for a 64 bits only system with the Xen
hypervisor.
I have first one question. If I am running host in full 64 bits only, can I
run for example Windows with some 32 bits applications ?
I tried to install everything properly and follow as possible the gentoo
wiki, but when I try to boot gentoo with xen, it doesn't work, I have the
error:
VFS: Cannot open root device

Just to explain, my laptop have a 500G SSD drive, partitioned in 3:
nvme0n1p1 for /boot/efi, nvme0n1p2 for /boot and nvme0n1p3 encrypted with
inside LVM, itself split in two logical partitions, 48G of Swap and the
left space for root.
Without Xen, my system boot properly (just to let you know)
This is my grub config (I think maybe it's where the problem start, because
I am not sure about my grub config:

Just to explain, my laptop have a 500G SSD drive, partitioned in 3:
nvme0n1p1 for /boot/efi, nvme0n1p2 for /boot and nvme0n1p3 encrypted with
inside LVM, itself split in two logical partitions, 48G of Swap and the
left space for root.
Without Xen, my system boot properly (just to let you know)
This is my grub config (I think maybe it's where the problem start, because
I am not sure about my grub config:

Last word, just to let you know, if I am able to boot with Xen properly, I
wish to install all dom in my external SSD /dev/sda (I commented it
actually under my /etc/fstab)
So what is my error in my configuration ?
