Subject: [PATCH] qemu: store complete agent filesystem information

In an effort to avoid holding both an agent and normal job at the same
|
|
|
d76c62 |
time, we shouldn't access the vm definition from within qemu_agent.c
|
|
|
d76c62 |
(i.e. while the agent job is being held). In preparation, we need to
|
|
|
d76c62 |
store the full filesystem disk information in qemuAgentDiskInfo. In a
|
|
|
d76c62 |
following commit, we can pass this information back to the caller and
|
|
|
d76c62 |
the caller can search the vm definition to match the filsystem disk to
|
|
|
d76c62 |
an alias.
