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 L1's hostname 'nested' input param to
differentiate 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.
Also, we use linux-stable tree as domain0 kernel source.
