[Qemu-devel] [PATCH v3 3/5] block: qemu-iotests - test for live migration |
Date: |
Thu, 10 Apr 2014 16:47:38 -0400 |
This is an initial, simple live migration test from one
running VM to another, using monitor commands.
This is also an example on using the new common.qemu functions
for controlling multiple running qemu instances, for tests that
need a live qemu vm.
