RH-Commit: [4/4] 8d31752d1e6e8c6a422d68d9cb2251fbc34b7aef (kmwolf/centos-qemu-kvm)
|
|
|
|
This tests that trying to resize an image with QMP block_resize doesn't
|
|
hang or otherwise fail when the image is attached to a device running in
|
|
an iothread.
|
|
|
|
This is a regression test for the recent fix that changed
|
|
qmp_block_resize, which is a coroutine based QMP handler, to avoid
|
|
calling no_coroutine_fns directly.
