Now I can easily determine wether I''m running on a modified kernel or not (by checking for the presence of /proc/xen). However, once I''ve found that, I''d like to know if I''m on a priviledged do...

When installing xen-utils-V in a driver domain domU, it drags in xen-utils-common, which also contains the init script for xenstored and xenconsoled. Installing the package will fail right away, because it exits non-zero after checking whether it's running in a xen dom0 or not: systemd[1]: Starting LSB: Xen daemons... xen[7215]: Starting Xen daemons: (warning). systemd[1]: xen.service:

Hi all, I''ve got a few questions : - can xend be started inside a modified guest? - can xend be started inside an unmodified guest? - what would be a simple way from a shell script to detect wether we''re inside a domU or a dom0? (taking into account the fact that the same kernel as reported, say, by "uname -a", could be running in the dom0 and the domUs) Thanks in

...--> domU fi fi Is parsing the output of ps, looking for xend, *once I know I''ve got a modified kernel*, an acceptable way to differentiate, *as a normal user*, between a dom0 and a domU? Oh well, anyway I think I''ll follow Andrew Ross''s advice of checking for control_d in /proc/xen/capabilities. I''ll just wrap the call to my shell script in an SUID executable (seen that "chmod +s" on a shell script has no effect) so that a non-root user can acces that info. thanks all and tell me if you have a cleaner way to do it, Jean ____...

Package: xen-utils-common Version: 4.4.1-9+deb8u4 Severity: normal Dear Maintainer, I have a server with a large number of domUs set to auto-start. For the first time I have booted it with all of them needing to start from cold, but the xendomains service only got part way through. syslog showed nothing notable about the domains starting? Apr 16 14:57:45 snaps xendomains[4631]: Starting

...Grub2 has then been setup to automatically boot the xen kernel. I''ve also had to add the option xsave=0 to the xen boot command line to get things to boot On restart everything looks good. "xl list" returns the Dom0 domain only. "cat /proc/xen/capabilities" returns control_d. I''ve created a windows 7 domU without any pci passthrough and successfully installed windows 7 ultimate. The config file looks like: builder=''hvm'' vcpus = 4 memory = 8192 shadow_memory = 48 name = "xenwin7" vif = [ ''bridge=br0'' ] acpi = 1...

Hi everyone, I am very excited to see that dom0 pvops is finally coming close to working, so I wanted to give it a try. >From the description it was not clear to me which kernel to chose as base for the patches.hg, so I took the latest (that was ~ 2 weeks ago) kernel on git.kernel.org I could find (post-2.6.28 git tip at that point). I managed to more or less apply all of the patches in the
