xen hypervisor wont boot from grub and "Can't find hypervisor information in sysfs!" error ubuntu 14.04
https://askubuntu.com/questions/532109/xen-hypervisor-wont-boot-from-grub-and-cant-find-hypervisor-information-in-sys
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:
