Import OVA or Virtual Image

[Miquel Gual Torner]

The OVA contains a CentOS 7 with kernel 3.10.
The import of the OVA works correctly.

qm importovf 612 ACR4_2_6.ovf local-lvm --format qcow2
  WARNING: You have not turned on protection against thin pools running out of space.
  WARNING: Set activation/thin_pool_autoextend_threshold below 100 to trigger automatic extension of thin pools before they get full.
  Logical volume "vm-612-disk-0" created.

But the machine doesn't turn on.

I have tested with machine i440fx, q35.
I have tested with BIOS: SeaBIOS or UEFI.

The best option is with BIOS SeaBIOS, then grub works. But it still doesn't turn on properly.
Booting with systemrescuecd and selecting the rescue option (findroot). Then the system turns on correctly. Everything works fine for me.

Problem:

[root@localhost lvm]# grub2-probe --device /dev/mapper/centos-root
grub2-probe: error: disk "lvmid/aCnmUs-YmCR-H6T2-qw18-elFp-51Wo-31pqkv/cuEd6N-uC5W-5Xsh-6HKq-j8ZI-XI06-B5FzEn" was not found.
Fix the problem with cfdisk. The partitions /dev/sda2 was not configured correctly (type).
[root@localhost lvm]# grub2-probe --device /dev/mapper/centos-root
xfs

Modify all LVM UUIDs (VG and LV). I still won't start.

grub2-mkconfig -o /boot/grub2/grub.cfg
grub2-install /dev/sda

But the system still doesn't boot correctly.
It seems that the kernel can't find the root partition that is in LVM.

 

[Miquel Gual Torner]

The kernel does not detect the hard drive.

Solution:

• bug grub2-probe -d /root/centos/root

cfdisk /dev/sda #change type to "Linux LVM"

• bug not detect the hard drive.
