Folks,
I am trying to boot Xen using efibootmgr on a Dell E6410 laptop with 4GB
RAM, running an Intel I5 dual core with VT and all the virtualization
options enabled.
It crashes almost immediately. I am working on getting the serial
console up so that I can get a more detailed stack.
A screenshot of the console is attached.
The xen.cfg file is:
[global]
default=xen
[xen]
options=console=vga,com1 com1=115200,8n1 dom0_max_vcpus=2 vga="qxl"
kernel=vmlinuz-3.8.13-48.el7uek.Other_EFI_v1.x86_64
root=UUID=917bfc7f-8d9c-4acf-a98a-a9f558daccf2 ro console=hvc0
enforcing=0 biosdevname=0 earlyprintk=xen nomodeset
ramdisk=initramfs-3.8.13-48.el7uek.Other_EFI_v1.x86_64.img
The codepath is "(gdb) x/20i get_cmos_time
0xffff82d080188825 <get_cmos_time>: push %rbp
0xffff82d080188826 <get_cmos_time+1>: mov %rsp,%rbp
