QEMU to have the option.
Unfortunatly, our documentation relie on QEMU's documenta

When LIBXL_SUSPEND_NO_SAVE flag is set, no savefile will be written, but
the domain will still be suspended (but not destroyed). The main reason
for this functionality is to suspend the host while some domains are
running, potentially holding PCI devices. This will give a chance to a

Hello,
We'd like to retrieve the length of the current instruction in
svm_vmexit_handler(), specifically for the VMEXIT_EXCEPTION_DB and
VMEXIT_EXCEPTION_BP cases.
We've combed the vmcb to no avail. Everything we've thought to check
(exitinfo1, exitinfo2, exitintinfo) turns out to be zero there w

In order to provide explicit synchronization between backend and

Protocol version was referenced in the protocol description,
but missed its definition. Fix this by adding a constant
for current protocol version.
