xen hypervisor wont boot from grub and “Can't find hypervisor information in sysfs!” error ubuntu 14.04












1















I have used This forum, trying to run xen on my os:



steps i have done :



egrep '(vmx|svm)' /proc/cpuinfo


ouput = 4 and also i have run KVM virtualization with no problem.



then:



sudo apt-get install xen-hypervisor-4.4-amd64 xen-utils-4.4 xenwatch xen-tools xen-utils-common xenstore-utils virtinst virt-viewer virt-manager 


then opened a console : Ctrl + Alt + F1 and :



sudo nano /etc/xen/xend-config.sxp


and appended to the last of the file these lines:



>     (xend-http-server yes)
> (xend-unix-server yes)


skipped the network part coz i will manage them when every thing is right by bridge control utility .



then



ln -sf /usr/lib/xen-4.1 /usr/lib64/xen


did reboot



in my ubuntu when i loaded booted after restart, whenever i insert this terminal code:



xm dmesg


i get the error of




ERROR: Can't find hypervisor information in sysfs!




in that forum and alot searches of google it says to configure the /etc/grub.d .



i did these steps for:
attempt 1:



sudo mv /etc/grub.d/10_linux /etc/grub.d/50_linux
update-grub2


attempt 2:



dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen
update-grub


Attempt 3:



mv /etc/grub.d/10_linux /etc/grub.d/20_linux && mv /etc/grub.d/20_linux_xen /etc/grub.d/10_linux_xen


but even with that it gives the same error.



when i try to boot from xen hypervisro which has appeared in boot grub loader, no matter what kind of xen hypervisor boot loader i select, system goes plank (or purple color of ubuntu default color) and never starts.



is there any particular solution?



P.S:

Although the community wiki states that as of Ubuntu 14.04, GRUB will automatically choose to boot Xen first if Xen is installed, it doesn't if you don't run Ubuntu (16.04) in English.



To be able to select the right kernel at boot open /etc/default/grub



sudo nano /etc/default/grub


and comment out the following 2 lines by putting a # in front of it and set GRUB_TIMEOUT to let's say 5



#GRUB_HIDDEN_TIMEOUT=0
#GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=5


next update Grub and reboot



sudo update-grub
sudo shutdown -r now


You should now be able to to select the right kernel in the grub menu and boot your system with Xen enabled. If you want to boot your system with this kernel by default write down the translation of "Ubuntu GNU/Linux, with Xen hypervisor". In my case (Dutch) that's "Ubuntu GNU/Linux, met Xen-hypervisor" and open /etc/default/grub.d/xen.cfg when booted.



sudo nano /etc/default/grub.d/xen.cfg


Replace GRUB_DEFAULT="Ubuntu GNU/Linux, with Xen hypervisor" with GRUB_DEFAULT="translation" at the bottom of that file and undo the changes you made in /etc/default/grub. Update Grub again and reboot with Xen enabled by default ...
