similar to: recommended offload settings

I am currently running a Redhat Rel5 Dom0 with a solaris 11-66 xen domU as well as a Redhat REL4 domU. I am experiancing problems similary to those described the the Aug 2006 Release notes regarding ... Solaris domUs on non-Solaris dom0s 32-bit Solaris domUs should run on any 3.0.2-3 or later dom0. The majority of our testing has been on CentOS dom0s. 64-bit solaris dom0 and domU require updates

In my Linux VM, I am unable to change scatter-gather / tx-checksumming / TCP-segmentation offload features by ethtool command. I am using virtio nic with vhostuser port backend. It shows me an error: Cannot change tx-checksumming Cannot change scatter-gather Cannot change tcp-segmentation offload Could not change any device features Ony running command ethtool -k ens3, I get the following:

Hello Xen folks, I have independently verified that this patch indeed fixes the issue (I posted a message about the issue over the summer: http://lists.xensource.com/archives/html/xen-devel/2005-08/msg00114.html). I used changeset 8911 of xen-unstable.hg. The patch as written expects kernel linux-2.6.16-rc2, but changeset 8911 uses kernel 2.6.16-rc4. I verified that the patch works with

I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

Now that we have SCTP offload capabilities in the kernel, we can add them to virtio as well. First step is SCTP checksum. We need a new freature in virtio to negotiate this support since SCTP is excluded with the stardard checksum and requires a little bit extra. This series proposes VIRTIO_NET_F_SCTP_CSUM feature bit. As the "little bit extra", the kernel uses a new bit in the skb

Split IPv6 support for UFO into its own feature similiar to TSO. This will later allow us to re-enable UFO support for virtio-net devices.

Hello! Has anybody experienced network latency problems with combination of Windows 7, GPLPV drivers and RDP connection? Any Windows pop-up message(such as "command not found" error message in "Run command:" dialog, or dividing by zero in windows calc) causes a short freeze of RDP session and looks like that from dom0: PING 192.168.44.65 (192.168.44.65) 56(84) bytes of data.
