Subject: [PATCH] qxl: Ignore set_client_capabilities pre/post migrate
|
|
|
|
The recent introduction of set_client_capabilities has broken
|
|
(seamless) migration by trying to call qxl_send_events pre (seamless
|
|
incoming) and post (*) migration, triggering the following assert:
|
|
qxl_send_events: Assertion `qemu_spice_display_is_running(&d->ssd)' failed.
|
|
|
|
The solution is easy, pre migration the guest will have already received
|
|
the client caps on the migration source side, and post migration there no
|
|
longer is a guest, so we can simply ignore the set_client_capabilities call
|
|
in both those scenarios.
|
|
|
|
*) Post migration, so not fatal for to the migration itself, but still a crash
|
