This commit delays the point at which bdrv_new (and hence blk_open on the underlying device) is called from blk_init to blk_connect. This ensures that in an inbound live migrate, the block device is not opened until it has been closed at the other end. This is in preparation for supporting devices with open/close consistency without using O...

Hello! I was asking for help on the Freenode channel, and I was pointed here. I have a situation where, using xl, I can create a functional PV domU, with or without pv-grub, but I cannot access the console. Firing up xend and using xm works without trouble. Since xend and company is being deprecated, I would like to transition to using the xl toolstack. The system is an Arch Linux system
