[Xen-devel] [OSSTEST Nested PATCH 0/6] Introduction of netsted HVM test job

["longtao.pang" <longtaox.pang@xxxxxxxxx>]

This patch set adds nested HVM test case for osstest.
In this test case, a Xen hypervisor (L1) runs on top of another Xen hypervisor 
(L0). 
Upon L1 hypervisor, we will then create a nested guest (L2), and test if the 
Linux guest can then be installed and run well.
About nested Xen virtualization, refer to 
http://wiki.xenproject.org/wiki/Nested_Virtualization_in_Xen.

Test steps
        0. To run osstest in standalone mode, write a config file in
           '~/.xen-osstest/config', and then create a standalone.config file to
           define 'TREE_LINUX', 'REVISION_LINUX' and 'NESTED_OS_IMAGE' which
           will be used for nested test. The directry path of 'Debian Images'
           could be difined in '~/.xen-osstest/config'. 
        1. run 'build-amd64' job and then 'build-amd64-pvops', to prepare xen
           installation tarball and hvm guest kernel.
        2. run 'test-amd64-amd6-nested' job, it does following:
                a. invoke test step of 'ts-debain-hvm-install' to install 
                   a normal HVM guest
                b. invoke test step of 'ts-nested-setup' to make some
                   appropriate runvars which selecthost would recognise and
                   prepare the configurations for installing L2 guest VM. 
                c. invoke test step of 'ts-xen-install' to install xen on 
                   the normal guest, alter it into a L1 hypervisor
                d. invoke test step of 'ts-debain-hvm-install' again, but 
                   take the L1 hypervisor as host, install the L2 guest on it
                e. invoke test step of 'ts-guest-stop', stop L2 guest.
                f. invoke test step of 'ts-guest-destroy' to destroy L1 guest.

This patch set reuses 'ts-debian-hvm-install' for both L1 installation and L2 
installation, define 'nested' and 'nested2' as L1 and L2's hostname, define 
'nested_l1 as L1's host ident.
It also reuses 'ts-xen-install' with 'nested' input param to differentiate L1 
Xen installation from L0 Xen installation.
This patch series has been tested on test machines of amd64 arch, 
debian-7.6.0-amd64 as guests OS, with hvm domain0 of Linux kernel 3.18.5, in 
standalone mode.
