Hello Michael,

whether we can just use HIGHDMA flag to enable zero-copy in macvtap to
avoid the new flag for now since mavctap uses real NICs as lower device?
When we have a MMIO exit, we need to find which device
has registered to use the accessed MMIO space.

Hello Michael,
Looks like to use a new flag requires more time/work. I am thinking
whether we can just use HIGHDMA flag to enable zero-copy in macvtap to
avoid the new flag for now since mavctap uses real NICs as lower device?
Is there any other

Hello Dor,
Let me see if I understand live snapshot correctly:
If I want to configure a VM for daily backup, then I would do
the following:
- Create a snapshot s1. s0 is marked read-only.
- Do a full backup of s0 on day 0.
- On day 1, I would create

Hi,
If I start a KVM instance with -vnc none -serial null options, I can
start a vnc server at a later time using the QEMU monitor's change
command. Is there a way to also redirect the serial device elsewhere,
like a telnet server?
Thanks,
Michael.

giveup_spe() saves the SPE state which is protected by MSR[SPE].
However, modifying SPEFSCR does not trap when MSR[SPE]=0.
And since SPEFSCR is already saved/restored in _switch(),
not all the callers want to save SPEFSCR again.
Thus, saving SPEFSCR should not

passed as a separate macro parameter, allowing reuse with other SPE

BKeep the guest MSR and the guest-mode true MSR separate, rather than
modifying the guest MSR on each guest entry to produce a true MSR.
Any bits which should be modified based on guest MSR must be explicitly
propagated from vcpu-arch.shared-msr to vcpu-arch.shadow_msr in

This is done lazily. The SPE save will be done only if the guest has
used SPE since the last preemption or heavyweight exit. Restore will be
done only on demand, when enabling MSR_SPE in the shadow MSR, in response
to an SPE fault or mtmsr emulation.
