Note there are couple of places left untouched because those

Both @accel2d and @accel3d are parsed as virTristateBool, but in

type. Clear this confusion by using the correct enum.

This reverts commit 938382b60a.
Turns out, the commit did more harm than good. It changed
semantics on some public APIs. For instance, while
qemuDomainGetInfo() previously did not returned an error it does
now. While the calls to virProcessGetStatInfo() is guarded with
virDomainObjIsActive() it doesn't necessarily mean that QEMU's
PID is still alive. QEMU might be gone but we just haven't
realized it (e.g. because the eof handler thread is waiting for a

In this rare case we can make the XML parser more strict, as libvirt
would never format the '<acpi/>' element if the index is '0' thus there
are no libvirt-generated XMLs we'd not load back, as of such this is
identical to rejecting it in the validation phase.

that for any string that's not recognized a negative one is

can be sure that all enum members are covered. Therefore, there
is no way that virXXXTypeFromString() can return a value that's
bigger or equal to VIR_XXX_LAST.
