Re: [Libvirt-cim] [PATCH 3 of 3] [TEST] #2 Fix VSMS 08_modifyresource.py on Xen and KVM

# HG changeset patch # User Kaitlin Rupert <karupert(a)us.ibm.com&gt; # Date 1213907999 25200 # Node ID 6bbf46ffb58f0de81ff2606c5c27284d3b997ed2 # Parent 1ea2eaa7349fb3c16281c4071b252104c7fde5c2 [TEST] #2 Fix VSMS 08_modifyresource.py on Xen and KVM. This still fails on XenFV because of a provider bug. It looks like the ModifyResource call strips the <emulator> tag from a XenFV guest. So the test is unable to start the guest. Updates to this test: -Call create_netpool_conf() to create a new network pool to use in modify calls. -Create network RASD instead of bridge -Replaced modify calls with functions from vsms_util -Added support for modifying a running guest (mem and vcpu only) -Remove XFAIL Updates from patch 1 to patch 2: -After undefining the guests in the loop, get a new XML object so the guest is defined using a default XML (not a modified one). -Instead of changing vcpus from 1 to 3, start out with a 2 vcpu guest and change down to 1. This ensures that the guest is a SMP guest starting out. -Instad of changing memory from 128 to 78, use 128 to 256 instead. 78 isn't much memory for a guest to run.
