grub with qemu-kvm server fail

grub with qemu-kvm server fail

[ng0]

Hi,

I already contacted the hoster support, but maybe someone has an idea.

Upon initing GuixSD from a minimal Debian base, I get stuck at this point
about GRUB. The server is aparently a qemu -> kvm one.

guix system: warning: while talking to shepherd: No such file or directory
Installing for i386-pc platform.
grub-install: warning: File system `ext2' doesn't support embedding.
grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.
guix system: error: failed to install GRUB on device '/dev/vda'

What kind of device is /dev/vda?

It looks like grub is trying to install itself on an ext2 partition rather than on the device itself (for old school dos partitions that would be in the MBR), and apparently this is not supported. I think I had a similar problem when installing on my personal computer with ext4; I think it was because I had specified a numbered partition rather than the device itself (/dev/sda1 instead of /dev/sda for example).

If I knew, I would've succeeded. I asked if there were any special requirements to the server ;)

There was just /dev/vda, no partitionsm, in a ready to be used system.

Of course in grub-configuration I wrote "/dev/vda" and in the file-systems the same.

And now I know:

"If you chose an autoinstall then there is no GRUB being used, the bootloader uses a kernel residing on the host."

But I have options to proceed.

Interesting! Good luck setting it up :)
