Inter VM communication
Hi: I have two HVM domU ubuntu 10.04 Lts and Window XP running. I have assigned PCIe device to each of this domU. I would like to communicate these two VM. Can anyone give me some idea on how to do. I did some research on IVC but unable to get answer. Anything will be appreciated.

PCI e Passthrough
Hi :
I am trying to do PCIe passthrough on HVM domu. I have window XP as a HVM domu and xen-4.0. dom0 and domU (without device assign) works fine.
I have more than one NIC card. I want to passthrough 03:00.0 to domu
here are the list of my nic cards:
lspci | grep -i eth
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)

RAM disapeared?
Hello,
I have some dom0 which have 8GB RAM, but when I look with xm list, it
just shows me 6GB,
I need to setup some new VM, each with 1GB, so I should have with 3VM
still 5GB free,
but im only seeing 3GB.
Can I just create 2 new VM with each 1GB and still have 3GB for the dom0?
#xm top
xentop - 11:31:17 Xen 3.1.0-53.1.14.el5
4 domains: 1 running, 3 blocked, 0 paused, 0 crashed, 0 dying, 0

Run multiple VMs
Hi:I am stuck here. I want to run two VMs (linux and window) concurrently. When I run them separately one at a time it works fine. But when I do xm create vm1.cfg then the domU starts and again if I do xm create vm2.cfg it just stucked and need to restart it. I am using live cd for vm2.
I am guessing I am missing some steps here. I will appreciate your help.

Put virbr0 in promiscusous
Hi ,
I have two virtual machines VM1 and VM2. Then I have added eth0 of my VM
to 'default' network.
Use case :-
I want to monitor all traffic on virbr0('default' network).
Steps followed :-
1. Add VM1 eth0 to virbr0
2. Add VM2 eth1 to virbr0
3. brctl setageing ovsbr0 0 ..(To put bridge in promiscuous)
Now I am running tcpdump on eth1 of VM2 and trying to ping

Zerocopy VM-to-VM networking using virtio-net
[It may be necessary to remove virtio-dev at lists.oasis-open.org from CC
if you are a non-TC member.]
Hi,
Some modern networking applications bypass the kernel network stack so
that rx/tx rings and DMA buffers can be directly mapped. This is
typical in DPDK applications where virtio-net currently is one of
several NIC choices.
Existing virtio-net implementations are not optimized for VM-to-VM

No, not on top of ivshmem. On top of shared memory. Our model is
different from the simplistic ivshmem.

[PATCH net] vhost: net: switch to use data copy if pending DMAs exceed the limit
We used to stop the handling of tx when the number of pending DMAs
exceeds VHOST_MAX_PEND. This is used to reduce the memory occupation
of both host and guest. But it was too aggressive in some cases, since
any delay or blocking of a single packet may delay or block the guest
transmission. Consider the following setup:
+-----+ +-----+
| VM1 | | VM2 |
+--+--+
