We were recently setting up CloudStack in our office for training and testing with the cloud infrastructure and we used Citrix XenServer as our hypervisors. To our pleasant surprise installation on MacMinis went on without any problems. However during the first boot we were presented with black screen and flashing file folder icon with a question mark in the middle.
After some research we’ve found a simple solution to this problem. Here’s what to do.
- Start your MacMini from Recovery by holding down the Command and R keys at startup.
- Open Terminal window by selecting Utilities menu and then Terminal.
- Type bless –device /dev/disk0s1 –setBoot –legacy and press enter.
- Restart your computer i.e. type shutdown -r now.
Although ridiculously, the bless command gets the job done, so bless your discs and use XenServer on Mac.
