[PATCH] qemu: Fix maximum physical address size in baseline CPU
Posted by Jiri Denemark 2 weeks, 6 days ago
We should include maximum physical address size in the CPU definition
created by virConnectBaselineHypervisorCPU only if we know the value for
all input CPUs. Otherwise we would create a CPU definition that is not
usable on all hosts from which we gathered the CPU info.
