Current status is that gentoo (using minimal iso with openrc as stage 3) vm won’t boot. It enters grub menu but afterwards says Block device UUID=xxxxxxxx is not valid root device. Could not find the root block device. Offers to drop into shell. I have tried inserting many different device descriptors, e.g., /dev/vda1 etc with no success.
In looking at grub commandline in the vm using (e), the grub command there has a different UUID string in the --set=root setting than what was listed later.
I have many other qemu vms working fine including TW so I am confident my basic setup works. I have configured/compiled gentoo vm probably 30 times using gentoo handbook and multiple successful installs in youtube videos. Followed steps very carefully. Tried both mbr and gpt disk partitions.
I am looking for a means to get information to point current vm to the root or perhaps there is some vm manager setting specially needed for gentoo vm that I am missing. Else maybe some means to modify files within the vm to correct things.
