Hi,
I am trying to run a PCI card as a pass-throughed device. The PCI driver
works well on physical PC but failed on a full-virtualized PC. The KVM
confiuration is OK as a pass-throughed network card works. I debuged the
PCI driver and found that the some registers of this PCI card should be
Hi all,
I have bridged the network of the host. There was one br0 and several
taps on it. When I started up a guest using:
#kvm -hda ubuntu.img -localtime -m 1G -net nic, -net
tap,ifname=tap0,script=no
The guest can ping to other VMs or physical PCs within the same
Hi Cam,
Does nahanni support asynchronous communication between multi-guests in
the same machine? Besides, is the Nahanni-MPI latency in your slide
Nahanni: a shared memory interface for KVM the average result or the
maximal result?
Thanks,

The CPU isolation in Hitachi patches is just to improve the real time
performance of GUEST. The core of it, direct IRQ delivery, is very similar
to that of ELI.
For the ELI patches,
(1) Since EOI part of ELI is already supported by the Intel Sandy
Bridge CPUs and requires modifications
Hi all,
When 2 VMs are started on the same network bridge, will the TCP/IP
packets between them still go through the router (actually these 2 VMs
share the same physical network card)? If so, is it possible to just pass
the packets inner the network card?

Hi,
I wonder if there is any detailed performance report of KVM
passthrough. I was just told it can achieve near native hardware
performance and could not get any experimental results.
Best,
Yi
So is my command line to start the guest OK? The command line is as:
qemu-img -boot c -hda readhat.img -device pci-assign,host=XX:00.0
Why doesn't the network work?

Hi all,
I am trying to implement pci passthrough for network card according to
this guideline:

The configuration steps were all ok. However, when I started the guest

Hi all,
I am running a netbsd kernel in KVM, using Intel VT. However, the OS
failed to start up with the following outputs:
KVM internal error. Suberror: 1
emulation failure.

Hi all,
I am trying to management the VMs created by KVM commandline. However, I
found the libvirt cannot connect to the VMs or manage it from virsh. Can
anybody provide any help?

Since the newest Intel-VT supports the guest OS under the real

support that case?
Yes, both with our without that unrestricted guest support

Hi Avi,
According to your reply if the CPU supports the real mode, the KVM can
support the real mode guest and there is still work to be done for CPU
without real mode support (i.e., software emulation)?
Thanks again,
Yi

Hi all,
I am trying to run Vxworks on KVM under X86_64 platform. Now I can
startup vxworks without 'no-kvm' option. However, the bootup failed with
hardware virtualization selected. Has anybody run it successfully?
Any of your suggestions would be appreicated.

Hi Bill,
I am trying to run vxworks on KVM with X86_64 machine. I've downloaded
your binary Vxworks Image from
http://lists.gnu.org/archive/html/qemu-devel/2009-06/msg00401.html
and ran it by: *qemu -fda vxworks.img*. Unfortunately, I could not bootup
the vxworks. The vncviewer shows that:
