similar to: RFC: Still TODO for 4.2?

I''ve migrated my Dom0 host to Xen 4.2.0 + xl toolstack. With ''xm'' toolstack, configs in /etc/xen/auto are autostarted, assuming xend/xendomains services are started. IIUC, when using xl toolstack, those services are not to be started; and, afaict, the installation process for 4.2 has them disabled by default. Now, the configs in /etc/xen/auto are simply ignored. I

Hey, I thought there was supposed to be an ability for domU''s to be put into a hibernated state (E.g. current running tasks and memory) when dom0 is shutdown or rebooted. When I look in my /etc/default/xendomains file, I have the variable''s "XENDOMAINS_SAVE=/var/lib/xen/save" and "XENDOMAINS_RESTORE=true". However, when I reboot, I always have to restart my

The contents are the wip.testme branch currently on salsa. I combined the wip.initscript and wip.oxenstored into this and added more things today. I think this is pretty gtg and it's smoke tested (in several cases by scping files around instead of doing package build), so it needs a final extra review and test round before putting it in master branch (which I don't want to force push). I

Hi, Here are three small but important libxl/xl memory management patches: - libxl: xl mem-max et consortes must update static-max in xenstore too, - xl: Allow user to configure xl mem-set behavior, - xl: Improve xl documentation in regards to guest memory management. Daniel

Hi, I''m using a custom block script in my xen setup and when started, it creates a new device node pointing to some network resources. Now I noticed that the script is called twice for the root block, the first time for pygrub most likely, but is only stopped once ... I don''t mind creating two devices node, but then I need to destroy both ... Is this a known issue ? Cheers,

This patch series adds support for network buffering in the Remus codebase in libxl. Changes in V3: [1/5] Fix redundant checks in configure scripts (based on Ian Campbell''s suggestions) [2/5] Introduce locking in the script, during IFB setup. Add xenstore paths used by netbuf scripts to xenstore-paths.markdown [3/5] Hotplug scripts setup/teardown invocations are now

Hello, Fedora 19 running Xen 4.2.3 rpms, "xl list" after dom0 reboot: [root@localhost ~]# xl list Name ID Mem VCPUs State Time(s) (null) 0 1024 8 r----- 16.3 Why is dom0''s name "(null)" ? It seems also xenstore is quite empty: [root@localhost ~]# xenstore-ls tool =

Just out of annoyance more than curiosity, but ever since I started using Xen 4.2-unstable rev-25467, every time I try to run "sudo xl create <domu_config_file>", or "sudo xl reboot", or "sudo xl destroy", it always gives me this message: "*xend is running, which prevents xl from working correctly. If you still want to force the execution of xl please

This is a patch to forward-port a Xend behaviour. Xend writes IO ABI used for all frontends. Blkfront before 2.6.26 relies on this behaviour otherwise guest cannot boot when running in 32-on-64 mode. Blkfront after 2.6.26 writes that node itself, in which case it''s just an overwrite to an existing node which should be OK. In fact Xend writes the ABI for all frontends including console

Based on Waldi''s RFC at http://lists.xen.org/archives/html/xen-devel/2012-09/msg00943.html To use it set vif.default.script="vif-openvswitch" in /etc/xen/xl.conf or use script=vif-openvswitch in the vif configuration. Appears to do the right thing for PV and HVM guests (including tap devices) and with stubdomains. In order to support VLAN tagging and trunking the

Moving to public discussion... This was found with Xen hypervisor version supporting device unplugging and the domU kernel having net-/blkfront and pci platform built-in (or as module). The block device is defined as hda and the NIC type=ioemu (so theoretically guests without pv support would work, too). Since both drivers are present, the kernel tries to unplug the emulated devices and

Hi - I''m trying to use the instructions here http://xen.pablolibo.com/doku.php to create a new VM but it''s not clear where the .cfg file should go and what to do next. I was thinking xe needs to install the vm from the /mnt/so_xen mount but i''m not sure. Are the steps on the site reasonable? Is there a way to install a vm from USB instead?  I don''t have an

$ git checkout RELEASE-4.2.2 $ git clean -ffdx [do a build, install, reboot] $ xl create a0 $ xl cd-eject a0 hdc [However, the guest OS still sees the CD inserted] $ xl block-list a0 Segmentation fault $ xl cd-insert a0 hdc file:/images/xs-tools-6.0.0.iso Segmentation fault The problem seems to be that xl cd-eject is writing corrupt values to xenstore. Note that vbd/1/5632 is still there

Hello, Third version of the NUMA placement series Xen 4.2. All the comments received during v2''s review have been addressed (more details in single changelogs). The most notable changes are the following: - the libxl_cpumap --> libxl_bitmap renaming has been rebased on top of the recent patches that allows us to allocate bitmaps of different sizes; - the heuristics for deciding

Hi, Ever since xl become the preferred toolstack, I have had problems using the xendomains startup/shutdown script. Having retested today, it seems that the issues are now reduced down to xendomains being unable to restart previously saved domains. Here is a typical session using xl running Xen 4.2.2 on Ubuntu 64 12.04 bit server, using stock Dom0 kernel (3.2.0-43-generic)

Prevent xl from doing any operation if xend daemon is running. That prevents bugs that happened when xl and xend raced to close a domain. Changes since v1: * Add documentation to xl man page. * Permit the execution of commands that don''t modify anything. * Indent error message.

Hello! I was asking for help on the Freenode channel, and I was pointed here. I have a situation where, using xl, I can create a functional PV domU, with or without pv-grub, but I cannot access the console. Firing up xend and using xm works without trouble. Since xend and company is being deprecated, I would like to transition to using the xl toolstack. The system is an Arch Linux system

Hi everyone, I''m trying to start up domU on xen for ARM (Cortex-A15 Fast models). I follow the instructions to build xen-tools with this link: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/CrossCompiling. But there seems to be something wrong when I start up domU. First, I get errors in create domU with xl: root@(none):/home/xiaogw# xl create domU-config xc: error:
