[pve-devel] [PATCH qemu-server 5/5] fix #5440: hmp helpers: drive{add, del}: increase timeout

[Fiona Ebner]

The default timeout for HMP commands is 5 seconds.

While it should be rather fast to attach a new drive to QEMU, a busy
system might take longer, so future-proof and increase to 60 seconds.

On the other hand, detaching a drive needs to complete any pending IO
on it, so use the same 10 minutes timeout that's used for
drive-related QMP commands.
