similar to: how to build Xen for 2.6.8.1?

I''m getting an odd kernel panic which I cannot get the whole error for, I believe it has something to do with a designation for the root filesystem. About the time it would be mounting the root filesystem, there is a kernel panic and it reboots less than 1 second later. I have lokoed around for dmesg logs and tried using the magic PAUSE, but with no luck. Recommendations? I

Hi, I want tested Xen with my OS based on a kernel 2.4 (it''s a CentOS 3.4). I downloaded the unstable sources of xen (xen-unstable-src.tgz). I read the user guide and I verified the "Prerequisites", I''ve : - the "iproute 2" package - the "linux bridge utils" - an installation of Twisted - gcc, binutils & make -

Another checksum offload problem was reported on xen-users, when using a domU as a firewall: http://lists.xensource.com/archives/html/xen-users/2006-04/msg01150.html It also fails without VLANs. The path from dom0->domU with ip_summed==CHECKSUM_HW/proto_csum_blank==1 is broken. - skb_checksum_setup() assumes that a checksum will definitely be calculated in dev_queue_xmit(), but the

> I''m guessing that the initrd created for dom0 in general > won''t work for > domU domains. I''m not sure what to do about that. If this is a -xen kernel, we should create a an initrd that can be used by both dom0 and domU, i.e. it has the necessary hardware drivers, but also the front end drivers. Aren''t there various differences between different

hi, i''m having here the problem with bonding and crcchecksum. So as i read the mailing list the solution is to run ethtool -K eth0 tx off inside domU. So my domU is reachable. All is fine. But after i migrate (live) the domU to another machine the complete domU stopped. Und I also had one time this ugly Zombie thing in xm list and couldn''t reboot the machine (only power

hi, i''ve a little problem here with raid1 inside domU. My setup is, two block devices (gnbd) attached to domU (sda1, sdb1) and build raid1 inside domU. All works fine (mdadm --remove, block-detach, resize, block-attach, mdadm -add) except the part where i want to grow my raid to the new size (mdadm --grow .. --size=max). Sometimes (when not much fs load is done in domU) it works and

While working bug #143, it came to my attention that no verbose error is loged if the dom0 kernel mangles a packet and tries to checksum offload it. This should let the user know what is going wrong (instead of silently dropping the packet).

Hello, A little informal input on the TCP/UDP checksum deferral/offload: it fails for me. I have one Xen host, running a snapshot of xen-unstable at 2006-03-24 (9435:11fee62328cc). Each of its domUs are allocated their own /30, with the help of a hacked-up vif script. Prior to working around the problem, Domain-0 could establish TCP connections to other domains. In the case of SSH, it would

Hi list, The crux of my setup is given in the Subject: field. I''m using Xen 3.0.3 (release) on a VIA Nehemiah chipset with Linux 2.6.16.29 in both dom0 and domU. Because the documentation on PCI passthrough is a bit sparse, I''m turning to the mailing list.. hopefully you guys have some input. My goal is to set up a system where: * 1 domU VM runs at a time. * The VM can be

There are a number of flaws in the blktap userspace daemon when dealing with I/O errors. - The backends which use AIO check the io_events.res member to determine if an I/O error occurred. Which is good. But when calling the callback to signal completion of the I/O, they pass the io_events.res2 member Now this seems fine at first glance[1] "res is the usual result of an I/O

I have two Xen 3.0.2 domains, both are using network-bridge, both servers are in the same network. dom0_A, domU_A - first Xen server (dom0 and domU) dom0_B, domU_B - first Xen server (dom0 and domU) I cannot ping or connect from one dom0_A to dom0_B nor domU_B. arping works fine though. I can ping and connect from domU_A to dom0_B and domU_B, though. I have changed

This set of patches adds the support for acceleration plugins to the netfront/netback drivers. These plugins are intended to support virtualisable network hardware that can be directly accessed from the guest, bypassing dom0. This is in response to the RFC we posted to xen-devel with an outline of our approach at the end of September. To follow will be another set of patches to provide our

A couple of years ago there was a discussion on lkml under the thread 'PATCH - ext2fs privacy (i.e. secure deletion) patch' about zapping deleted data in the filesystem as a security mechanism. The discussion wandered off into how 'chattr +s' could be implemented and whether encrypting filesystems wouldn't be a better solution to the problem. I've been maintaining a

You can have multiple vethX interfaces on recent builds -- see netback/loopback.c. I think the current default is a rather miserly 1 (and should be increased), but can be set on the command line.
