[bug #33762] can't install on virtio virtual device in KVM machine

[Bartosz Feński]

Follow-up Comment #2, bug #33762 (project grub):

Found a difference eventually!

Don't know why fdisk shows it in the way I though it's the same as on my other
machines.

cfdisk/parted show differences.

This is machine where I can install grub without problem:
serwer:~# cfdisk -P t /dev/vda
Partition Table for /dev/vda

         ---Starting----      ----Ending-----    Start     Number of
 # Flags Head Sect  Cyl   ID  Head Sect  Cyl     Sector    Sectors
-- ----- ---- ---- ----- ---- ---- ---- ----- ----------- -----------
 1  0x80    1    1     0 0x83  254   63 19458          63   312608772
 2  0x00    0    1 19459 0x82  254   63 19580   312608835     1959930
 3  0x00    0    0     0 0x00    0    0     0           0           0
 4  0x00    0    0     0 0x00    0    0     0           0           0
serwer:~#      

And this is problematic machine:

mainsrv:~# cfdisk -P t /dev/vda
Partition Table for /dev/vda

         ---Starting----      ----Ending-----    Start     Number of
 # Flags Head Sect  Cyl   ID  Head Sect  Cyl     Sector    Sectors
-- ----- ---- ---- ----- ---- ---- ---- ----- ----------- -----------
 1  0x80   32   33     0 0x83  254   63 39039        2048   627175552
 2  0x00    0    1 39040 0x82  254   63 39161   627177600     1959930
 3  0x00    0    0     0 0x00    0    0     0           0           0
 4  0x00    0    0     0 0x00    0    0     0           0           0
mainsrv:~# 

So seems it's not possible to install grub when first partiotion starts from
2048 sector. 

Is it bug or intended behaviour?
grub 0.x aka legacy works fine.
