...rking with my own script which creates 4 bridges ("$dir/network-bridge" "$g" vifnum=0 netdev=eth0 bridge=xenbr0 - this line I use four times for each interface). This works great so far. /etc/network/interfaces in dom0 brings only up eth2 with a static address (10.10.1.2). domU1 acts as router/firewall and has all bridges connected to it. And every ethX in domU1 has it''s own subnet (10.10.1.0/24 to 10.10.4.0/24). This works as well. My problem: Each time I download a lot of data (i.e. an apt-get upgrade which upgrades the kernel) in dom0, the network in dom...

Hello I use XEN 3.0 in debian sarge. I have a domU1 for routing and firewall. This domU1 use 2 network interfaces which is on a bridge ''gate'' and the other on bridge ''lan''. dumU2 use one interface (eth0) on bridge ''lan''. Then I make a ping out of domU2 to www.debian.de so I get no answer. Th...

...I am able to attach a disk device do a Xen domain, using virDomainAttachDevice(), running as a non-root user, but I am unable to use virDomainDetachDevice() - it results in an "unknown failure". Using "virsh [attach|detach]-device" exhibits this behviour. $ virsh attach-device domu1 attach.xml Device attached successfully $ virsh detach-device domu1 attach.xml error: Failed to detach device from attach.xml error: Unknown failure $ With some digging, I determined that the problem arises when libvirt tries to translate the device name to a number, using the XenStore API (xenS...

Hi, I have 5 very identical server running xen 3.0.3 (Debian etch std. packages) with serveral DomUs.

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 wit...

...at you are the author of the netback driver of linux-2.6.18-xen Dom0 and I hope I can get some help from you. I want to quickly have a knowledge about how a data packet is transferred between two VMs on the same Xen hypervisor if the TCP/IP protocol is used. I am not sure whether a data packet from DomU1 to DomU2 is transferred like this: DomU1(front-end network driver)-->Dom0(back-end network driver of DomU1)-->Dom0(Virtual bridge)-->Dom0(back-end network driver of DomU2)-->DomU2(front-end network driver) Is the virtual bridge in Dom0 in charge of forwarding the data packet to other D...

Hi all, I installed xen-3.3.1 and configured two DomU with 2.6.18.8-xen kernel. Now the DomU1 and DomU2 could work and the network is ok. But I used the filesystem image from jailtime, so the X-Window mode can''t work. Thus, I tried two ways to make the GUI-mode work: (1) yum install X-Window in Guest OS, and the GUI configuration Wizard shows up. When done with the configuration, t...

Hi, just upgraded my testsystem to 3.0.4 (using the provided source rpm, xen-3.0.4.1-1.src.rpm, rebuilt it to run on non-PXE but no changes besides that, and it doesn''t look like the 3.0.4-testing HG has major differences so far?) and I have two problems with rebooting domains (xm reboot, or reboot from inside the domain). 1) the kernel-commandline keeps growing. On the first boot

...riencing trouble with networking. Dom0 can reach the outside world when no DomU are started. It can also reach the outside world when only one DomU is running. The troubles begin when I start the second DomU. At first, this new DomU, called DomU2, can''t get outside. (at the time Dom0 and DomU1 are still reachable from outside). Once I get connected to DomU2 (console mode, xm console DomU2) and try to get outside, I''ll get through after a small amout of time. Nevertheless, this causes Dom0 to stop being reachable from the outside. Therefore when my two DomUs are running, there...

Hello, We''ve recently started seeing several domUs on multiple machines losing all network connectivity. At least one of these machines (since they are customer machines I can''t verify it for all of them) give the error: $ sudo ifup eth0 eth0: full queue wasn''t stopped!
