[PATCH V2 0/3] qemu: support update graphic device persistently

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We can change vnc password by using virDomainUpdateDeviceFlags API with
live flag. But it can't be changed with config flag.

v1: https://www.redhat.com/archives/libvir-list/2014-November/msg00627.html

diff to v1:

according to Jan's suggestion,
1. (patch 1/3) change error number to VIR_ERR_OPERATION_UNSUPPORTED
2. (patch 3/3) add 'VIR_DOMAIN_XML_SECURE' to flags in initialization.
3. (patch 3/3) Introduce a new function qemuDomainFindGraphicsIndex.
   Free the old graphics def and replace it with the new one as what
   we did for DEVICE_NET. 

Wang Rui (3):
  qemu: report properer error number when change graphics failed
  qemu: fix alignment of qemuDomainFindGraphics
  qemu: make persistent update of graphics device supported
