Hi, in the official XenNetworking ( http://wiki.xensource.com/xenwiki/XenNetworking ) i didn''t find reported how the NAT configuration works with xen. Does anybody know how the vifX.Y (10.X.X.128), gateway of any domU ethX (10.X.X.1) talk with the real ethX of the dom0?

...oblem with xen 3.0.1 compiled from sources on Debian Sarge, kernel 2.6.12.6 which can be easily reproduced at least on my installation: after I log in to domU console or via ssh and run "shutdown" I get deadlocked network interface with error message: unregister_netdevice: waiting for vifX.0 to become free. Usage count = n After this happen I can''t even reboot my dom0 via ssh because reboot process hangs (waits until interface is released but it never happens). I googled about this error and found some references to bridged networking problem (yes I use bridged networkin...

Hi all Really silly question here: do the vif interfaces require IP addresses? I''m totally stuck with getting IP traffic to my guest domain, layer 2 traffic (ie ARP queries/responces, broadcasts, etc) is all OK. Another question, what is peth0 used for?

...- if I attach a vif, the domU will not start Looking at /var/log/daemon.log, I notice: xcp-fe: qemu-dm-10[9169]: can't add tap10.0 to bridge xapi1: Operation not supported while the output from dmesg suggests that the interface vif10.0 was created. It appears there is confusion between the vifX.Y and tapX.Y naming schemes. Can anybody comment on this? Is this hardcoded into some config that I should inspect? Is it hard coded in the qemu-dm scripts? It would be very desirable to fix this before the wheezy release so that people don't have a bad impression of XCP with HVM. Regards,...

...ap0 for bridging isn''t being created.  This results in the CentOS 5.2 domU''s bridged eth0 only being able to ping the RHEL5 dom0''s IP address... but nothing else on the same physical NIC/subnet. Everything else is properly set in my dom0 in the sense that eth0, peth0 and vifX.0 are all there along with a "brctl show" which shows vifX.0 and peth0 bridged under eth0, but missing tap0 for the peth0/eth0. Anyone have any ideas?  Thanks! -- Daniel Kao Übermind, Inc. Seattle, WA, U.S.A. _______________________________________________ Xen-users mailing list Xen-...

Hi, I am experiencing a strange network problem. It looks like some packets get lost on the way from frontend network device in domU to the backend vifx.x in dom0. But first my configuration: - Xen 3.4.0 from the gentoo ebuild and the pvops dom0 kernel from jeremy/xen.git - The system has two physical network interfaces called gblan (Gigabit Ethernet) and felan (Fast Ethernet) - Two network bridges in dom0: gbbridge with the gblan interface and...

Hello, While using xen 4.1-testing.hg (r23202) I noticed that the ''vifname'' config value is not handled by xl, but is handled by xm. Is there a workaround or patch for this? My firewall and scripts depend on static vifnames. XM works good - it adds multiple interfaces to multiple bridges and configures them appropriately. But with xl it differs -- here only tap devices are

...: xen-utils-4.17 Version: 4.17.1+2-gb773c48e36-1 Severity: important Dear Maintainers, On one of our domUs we discovered that the network interface names were wrongly assigned since recreating the domU after an upgrade to bookworm. If over 10 network interfaces are configured the mapping (dom0) vifX.10 <-> eth10 (domU) does not apply anymore. Instead the interfaces on dom0 are sorted primarily by the leftmost digit. so for 11 interfaces we will end up with: vifX.0 <> eth0 vifX.1 <> eth1 vifX.10 <> eth2 vifX.2 <> eth3 vifX.3 <> eth4 .... This was observed...

Package: xen-utils-common Version: 4.1.2-3 Severity: normal When configurating a duplicate custom vifname for interfaces in the Xen dom0 that are added to a bridge (which is obviously a configuration error), the hotplug scripts fail silently to rename the new vifX.0 to the custom vifname, if it's already existing. The result of this, is that the domU will start normally, but no network traffic between domU and the dom0 bridge is possible, because the vifX.0 never gets added to the bridge. Worse... when doing xm shutdown on the newly created domU, while...

...network-bridge-vlan for multiple VLANs in domu. Several domu uses the bridge vlanbr30. Need to dom0 as was in this vlan''e. How? I tried to put a bridge interface ip, but with him until the rest domu in vlanbr30 not get through. How to understand the need to create a virtual interface (vifx.y) and add it to the bridge vlanbr30. How?

Hello, While testing Fedora 16 Xen PVHVM guests I noticed the following problem: When starting F16 PVHVM guest I can see the vifX.0 and tapX.0 interfaces appear on dom0, but after the guest kernel (Linux 3.1.0) starts and loads PVHVM drivers the vif/tap interfaces disappear from dom0.. so the bridge in dom0 doesn''t have any vifs/taps connected to it anymore. Has anyone seen that behaviour? I bet that''s...

...chines are not paravirtualized. The are fully emulated x86 hosts. This is achieved using the vif-bridge script that accompanies the xen-tools (I have emerged the xen-tools-3.4.2-r1.ebuild ebuild provided by gentoo portage). Each HVM client increments a new tapx.x interface, and also a corresponding vifx.x interface. I am not using the standard xenbr0 configuration that everybody else is talking about and using. My bridge looks something like the following: (cloud) | [wired-eth0]-----| |---------[br0 on XEN DOM0 HOST] [wired-eth1]-----| |...

Hi, this is propably bridge related and not really a xen problem, but it might help someone: Some of our domUs are not able to arp. Arp -n show (incomplete), and doing a tcpdump shows, that on the dom0''s eth0 the arp request goes out, the response comes in, but on the vifX.0 interface the arp response is gone. dom0# tcpdump -ni eth0 arp who-has 10.32.2.51 tell 10.32.7.70 arp reply 10.32.2.51 is-at 00:30:48:34:44:6c dom0# tcpdump -ni br0 arp who-has 10.32.2.51 tell 10.32.7.70 arp reply 10.32.2.51 is-at 00:30:48:34:44:6c dom0# tcpdump -ni vif3.0 arp who-has 10.32.2...

Hi all, With help from others, I''ve been able to get Olaf''s patch for enabling MTUs >1500 for vifX.y and tapZ devices working. I''ve been able to boot dom0, launch domU and live-migrate without having the bridge''s MTU degrade at any time. Would the Xen RPM maintainers (and others) mind taking a look at the following patches? Kernel part: https://bugzilla.redhat.com/show_bug....

Ok running Kubuntu 11.04, is it possible to get XEN 4.1 installed to virtual a laptop running Kubuntu ? I seriously dont want to use Vbox or KVM, and need to run other OS for development, so XEN virtualization on a 8 core laptop with 16 gig memory seem the best bet for mobile development _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com
