[pve-devel] [PATCH qemu-server 1/1] fix #6828: remote migration: bump timeout for writing configuration to accommodate volume activation

[Fiona Ebner]

The 'config' command will lead to volume activation being done for the
referenced volumes. This is because the 'config' handler in the
mtunnel API endpoint calls into the update_vm_api() function, which
uses the create_disks() function, which is also used for existing
disks. In create_disks(), each volume is activated to do an
existence/basic sanity check by querying its size.

There is no requirement to be fast when handling the 'config' command
during remote migration. Since there could be many disks for a given
VM, allow for up to 2 minutes instead of just 10 seconds.
