Hi, all. virtio-net has a sudden high latency when receiving. i think it is
irq related, but i have no idea to fix it.
centos 3.10.0-693.21.1.el7.x86_64 ; qemu-kvm-ev-2.6.0-28.el7_3.9.1.x86_64 ;
physical machine has 40 cpus, the two vms are on the same node, cpu load is
very low.

The bit 6, 7 and 8 of MSR_IA32_ARCH_CAPABILITIES are recently disclosed
for some security issues. Add the definitions for them to be used by named
CPU models.

It lacks VMX features and two security feature bits (disclosed recently) in
MSR_IA32_ARCH_CAPABILITIES in current Cooperlake CPU model, so add them.

Current Cooperlake CPU model lacks VMX features which are introduced by Paolo
several months ago, and it also lacks 2 security features in
MSR_IA32_ARCH_CAPABILITIES disclosed recently.

Hi all,
I tried to run Qemu-4.2 with pulse audio but faced issue
as there is no audio at all in guest .However it works fine with ALSA. I
tried the same in Qemu-3.0 with pulseaudio. It was working fine. But facing
issue after upgrading to Qemu-4.2. Any suggestions?
Thanks

Hm.. The hflags is a TCG thing tha

Public bug reported:
QEMU 4.2.0 compiled from source, Ubuntu 19.10, open a fresh new gnome
terminal.
If you print 1000 = chars on the host terminal, then they do wrap around
the end of the terminal:
printf "=%.0s" {0..1000}
However, if you first run QEMU:
x86_64-softmmu/qemu-system-x86_64 -nog
The MC146818 sits on an ISA bus. Since it can not be used
without it, select ISA in the Kconfig.

I’m trying to experiment with adding a Qemu devices (ethernet/NIC) and it’s
corresponding Linux driver. I’ve chosen to port the following ‘codeproject’
project:

Since this was written a couple of years back, it didn’t
Some guests read back queue size after writing it.
Always update the on size write otherwise they might be confused.
