Re: [Xen-devel] domU guest for xcp 0.1.1

[Ritu kaur <ritu.kaur.us@xxxxxxxxx>]

Hi,

I am running out of options to test pci passthrough with shared interrupts, since xen/next kernel doesn't work with xcp0.1.1 dom0. I tried couple of combinations

1. xen 3.4.3 with xen/next kernel, dom0 continuous reboot, boot messages goes off pretty fast so not sure what's going wrong here.

2. xen 3.4.3 with 2.6.27.42-0.1.1.xs0.1.1.737.1065xen(i.e which comes with xcp 0.1.1 default) system boots fine.

3. Assuming "1" is related to wrong .config file, copied kernel-2.6.27.42-0.1.1.xs0.1.1.737.1065-i686-xen.config which comes with dom0 kernel code, compiled and still same result as "1".

Note: All 3, I tested by copying just xen3.4.3.gz, tools and stubdom is not copied. If there is any viable options left to try out let me know.

Thanks

with 3.4.3 xen and kernel code from Jeremy's xen/next puts dom0 into continuous reboot mode.

1. downloaded xen/next code into DDK and generated tar-pkg, it generates linux-2.6.32.tar. Copied this tar file into root directory of dom0 and extracted the file.

2. Copied xen code from http://xenbits.xensource.com/xen-3.4-testing.hg into DDK and did "make xen", copied xen.3.4.3.gz into /boot of dom0.

modified extlinux.conf to point to new vmlinuz and xen. dom0 is in continuous reboot mode, let me know what am I doing wrong?

Thanks

Thanks Konrad. I downloaded kernel code from  xen/next. I believe this requires 3.4.3 or 4.0.0 xen hypervisor code, I downloaded xen hypervisor from xenbits.xensource.com/xen-unstable.hg. For xcp dom0 all compilation happens in DDK and no make utility is available and as I understand I need to execute make install-* in dom0. For install-xen probably I can copy xen.gz into /boot and modify files to reflect that but I am not sure what's the needed to install tools and stubdom in xcp dom0?

make xen
make tools
make stubdom

make install-xen
make install-tools
make install-stubdom

Thanks

Both.
