Subject: [PATCH] qemu: gpu: Get pid without binary validation
|
|
|
|
The binary validation in virPidFileReadPathIfAlive may fail with EACCES
|
|
if the calling process does not have CAP_SYS_PTRACE capability.
|
|
Therefore instead do only the check that the pidfile is locked by the
|
|
correct process.
|
|
|
|
Fixes the same issue as with swtpm.
