Issue:
After you import an linux image into openstack and run an instance of it, you may find that the startup is hang and get following error message:
MP-BIOS bug: 8254 timer not connected to IO-APIC
Root cause:
This is cause by Linux Timer Check function, which is not needed while becoming vm image.
Solution:
Try to disable timer check in grub configuration file. (Following steps are based on CentOS7; others are similar.)
1. vi /boot/grub2/grub.cfg (for other system, the file path may be '/boot/grub/grub.conf')
2. add 'no_timer_check' to following similar positions.
3. Once done, re-import this system as openstack image and create a new instance. The issue should be resolved.
