Description Yuxin Sun 2021-04-23 09:42:21 UTC
Created attachment 1774729 [details]
dual boot kickstart file

Description of problem:
When I use the kickstart file to build a BIOS+UEFI dual boot image, it cannot boot after installed.
I worked well with RHEL-9.0.0-20210414.0 but cannot work with RHEL-9.0.0-20210418.3 and later composes.

Version-Release number of selected components (if applicable):
RHEL-9.0.0-20210418.3 and later composes

How reproducible:
100%

Steps to Reproduce:
1. Prepare a dual boot kickstart file(see the attachment). Create a 10G qcow2 file:
# qemu-img create rhel-9.qcow2 10G -f qcow2
2. Create a .iso file and put the ks file in
3. Use virt-install to build the image:
# virt-install --name walatestimg --ram 2048 --network bridge=virbr0 --vcpus 2 --cdrom ks.iso --disk path=rhel-9.qcow2,bus=virtio --noreboot --boot uefi
4. Use virt-manager to boot it in KVM

Actual results:
1. First boot: can boot up and go to "login", but actually cannot login
2. After reboot, it hangs during boot:
systemd[1]: No /sbin/init, trying fallback
systemd[1]: Failed to execute /bin/sh, giving up: No such file or directory
systemd[1]: Freezing execution.

Expected results:
Can boot successfully.

Additional info:
If build a BIOS only image, it works well.

Hi Javier, 

Do you know of anything in grub2 from RHEL-9.0.0-20210418.3  (or later) that could impact dual boot image from booting?

Comment 2 Yuxin Sun 2021-07-20 12:50:25 UTC
Now I can use rhel-guest-image as a workaround. The rhel-guest-image is a dual boot image. So there might be something wrong in the kickstart file(although it worked well in RHEL-9 Alpha).

Removed testblocker keyword and change priority/severity to low.

Comment 3 Yuxin Sun 2021-09-06 07:52:49 UTC
Test in RHEL-9.0.0-20210905.7. It works now. Close this BZ.
