Xen project Mailing List

Hello all,

I am trying to build PVH mini-os with libc support. These are the steps I have followed so far:

1. Xen repo (master: commit id: d2f86bf604698806d311cc251c1b66fbb752673c)

2. mini-os repo (master: commit id: 0b4b7897e08b967a09bed2028a79fabff82342dd)
3. Made the following modifications in the xen repo to build c-stubdom:

4. $ cd $(XEN_ROOT)

5. $ make; sudo make instal
6. Reboot host
7. $ cd $(XEN_ROOT)/stubdom
8. $ make c-stubdom
9. Used the following configuration file to create the domain:

type="pvh"

memory=512

vcpu=1

name="minios"

kernel="/home/balvisio/xen/stubdom/mini-os-x86_64-c/mini-os.gz"

When I create the domain it crashes during the bootstrap process with a triple fault. The following are the dmesg logs (note that "Xen Minimal OS (hvm)!" is printed and the domain crashes after that line in setup.c):

Any help on this would be greatly appreciated. In addition to this I have noticed that even fter installing Xen and rebooting the host, the initial ‘xl dmesg’ logs show that Xen tries to launch unsuccessfully domains created before the system was rebooted. I am not sure if these two issues are related but I pasting a trace of the logs (these dmesg logs are seen just after rebooting the host before attempting anything else):
