Anthony, can you please share any patch that can help me with this?
>>>> Can you post the full output of the logs?
I have attached the output of "sudo xl -v create /etc/xen/qemu-pv.cfg"
as xl_create.txt. I have also enabled DEBUG_XEN_HVM in xen-hvm.c and pasted
output of "sudo ./x86_64-softmmu/qemu-system-x86_64 -machine q35,accel=xen
-cpu qemu64 -xen-domid 13" below:
xen: shared page at pfn feffd
xen: buffered io page at pfn feffb
bind interdomain ioctl error 22
xen hardware virtual machine initialisation failed
>>>> What is the Xen version that you are running?
I am using XEN 4.4.1 as this is the default on Ubuntu 14.04. I have
attached the output of "xl info" command as xl_info.txt.
>>>>Did you execute the xencommons init script at boot time?
On Ubuntu I don't see /etc/init.d/xencommon but there is a /etc/init.d/xen
script which starts xenstored and xenconsoled. I did confirm from ps aufx
that both the daemons are running. I have attched log for "ps aufx" as
ps_aufx_grep_xen.txt .
