DomU to DomU throughput issue
Hi
Is there anyone who has successfully resolved the low throughput problem in Guest communication.
I am using Xen3.4.1 with PV os kernel 2.6.30-rc6-tip On fedora11. While running netperf benchmark on guests throughput results are very low
DomU to DomU 0.29 Mbps
Why is it so? What would be the problem. Is there any issue with fc11 platform?

[Xense-devel] [RFC][PATCH][ACM] enforcing ACM policy on network traffic between virtual network interfaces
This patch adds an ACM hook into the network scripts (/etc/xen/scripts).
It adds iptables rules that enforce mandatory access control on network
packets exchanged between virtual interfaces. If ACM is active, this
patch sets the default FORWARD policy in Dom0 to DROP and adds iptables
ACCEPT rules between vifs that belong to domains that are permitted to
share (determined by using the

xen 4.1.1 missing veth0 <--> vif0.0 pairs
Hi,
I am using Xen 4.1.1 with Linux 3.0.1 kernel. Previously (Xen 3.4.4 and
linux kernel 2.6.18) Xen by default created veth0 <--> vif0.0 pair in dom0.
With Xen 4.1.1 these pairs are missing in dom0.
Using command ''ip link add type veth'' I can create veth0 and veth1 but
vif0.0 is still missing in dom0. (When new domU created I can see vif1.x
created)
Could you please help

Xen and DHCP problem
Hey folks!
I want to add a CentOS 5.2 domU to an existing server (Fedora 8) which was setup by another company. The Dom0 does not provide any other services but a BIND-DHCP-server (they deleted dnsmasq and installed bind). Don''t ask my why they did that.
My new DomU is connected to eth0, which is a bridge. BIND also listens on eth0 to serve other machines.
I start the install of centos

what the role platform-pci play in comunication between HVM and domain0
Hi,
Can someone interpret how HVM guest communicate with domain0, as i know, H VM can not use event channel directly, is the platform-pci offer a way to solve this?
Please try to explain concretely, for example :
1.how does HVM send a event to domain0, how does domain0 catch this event, and assoicate it with a handler
2.the opposite direction, how does domain0 send event to HVM guest? Does it

Creating network bridge without IP address
Hi everyone!
I have the following setup:
domain0
|-domU1
|-domU2
|-domU3
I am running this with libvirt on a XEN server. Right now the server is connected to our office network, but later it will be in a hosted environment. I need domU1 and domU3 to have a public IP, and all of the domUs and the dom0 should have an internal IP address to communicate with each other. So this is what I would like

bridging and peth0
Hi,
If one sets xend to use network-bridge and there are no bridges
already present then it seems that xend will clone eth0 to peth0,
create xenbr0 and add peth0 and vif0.0 as ports on that bridge.
If on the other hand xenbr0 is created in /etc/network/interfaces
then xend will not do any of that peth0 stuff, nor will it add
vif0.0 to xenbr0, yet (barring some changes in iptables rules)

bridge with IP address, "received packet with own address as source address"
Hi,
I''ve set up identical (what I think) machines using SLES 10 x86_64, but a new one
of those is saying frequently in /var/log/messages:
