FreeNAS 11 u4 and bhyve booting EFI CentOS 7 x64

[RegularJoe]

Hi All,

I do not know what I did, if the issue started because I deleted the VM and re-created it or because I installed a second VM on the same host, Debian x64 on a different ZVol or what. The Debian install is junk I can delete that, but the CentOS 7 install I spent some time in. It is a virtIO for the Nic and the HD. Very fast I might say when it is working.


Q1) my CentOS 7 x64 guest now forgets the EFI boot file every time, refind does not help to install as it gets lost by the boot manager too. Is there something I need to do in CentOS to have it save the last EFI boot as a permanent variable?
Q2) my VNC connection used to be fast... Now VERY slow on my mac wired or wireless.

A2) RealVNC works fine, TightVNC on Windows and ChickenOfTheVNC is slow...

Thanks
Joe

Clearly the EFI boot manager is looking for

/BOOT/EFI/BOOTX64.EFI

what I see after it boots :
/boot/efi/BOOT/EFI/BOOTX64.EFI

so is this a bug?

This should hopefully solve your boot problem:

# cp /boot/efi/EFI/centos/grubx64.efi /boot/efi/EFI/BOOT/bootx64.efi

See https://forums.freenas.org/index.ph...linux-vms-using-uefi.54039/page-4#post-409268

In short, use the shim efi file
EFI/boot/centos/shimx64-centos.efi

well since I installed refind on that VM I copied the BOOTX64.EFI from refind and that works now. Just doing a double look to see if when I shut down the HOST that my guest is getting a graceful shutdown.

sudo cp ../refind/refind_x64.efi BOOTX64.EFI
