Re: [Qemu-devel] Crash: When Host HDD is full

[Alexey Eremenko]

Pause VMs is the only realistic option. This is the correct option,
because it ensures that guest is still alive.
Other options might crash the guest, like Windows BSOD. Worse yet is
that guest may think that it's hard disk is bad, and will start
marking it's sectors as bad-blocks.

When the VM is paused, the user may take action to free some disk
space and unpause guest manually.
