If the guest is unresponsive and 'info balloon' is invoked, the monitor
process just hangs waiting for info from the guest. Return the most
recent balloon data in that case.
A new timer is added, which on expiry, just presents the old data to the
monitor callback functions.
See https://bugzilla.r
Since I didn't get negative reactions to the patch I posted yesterday,
here's the complete series. It adds a qerror message that mentions the
machine is stopped or the guest is slow to respond, so the stats
should be assumed to be old.
The error report is sent out before the stats, I don't think w

Hi, all
I want to setup a mips development environment for Freebsd. The gxemul is so
slow and no networking support. I want to transfer to qemu, unfortunately
qemu can't load the freebsd kernel, and there is no mips bios bin file. Is
there any plan to support the mips bios? It is appreciated if so

On KVM for PPC we need to tell the guest which instructions to use when
doing a hypercall. The clean way to do this is to go through an ioctl

For a crashed/oopsed guest even 10 seconds may be okay, as long as it's
