[PATCH 0 of 1] [TEST] Don't send commands via ssh for localhost

by Eduardo Lima (Etrunko)

Alright, this patch has been around for a while and I think the results are very similar to the version which sends all commands via ssh, except for the performance boost. I am now sending the patch for appreciation and requesting some feedback, especially if there is any specific test that was working but is now broke because of this patch. If possible, run the full cimtest suite first in a pristine checkout and save the run_report.txt file with a different name. After that, apply the patch to the tree and run the suite again. Reply to this email attaching both files so we can analyse the results.

[PATCH] (#2) Add write support for FilterList and NestedFilterList

by Chip Vincent

# HG changeset patch # User Chip Vincent <cvincent(a)us.ibm.com> # Date 1309213800 14400 # Node ID 2a1c7e5112590eb7157b566facd61ea9fc815b85 # Parent 75411f53df02159c3fa6ce5810c9446579e3d66d (#2) Add write support for FilterList and NestedFilterList Changes since #1: - fixed compilation issue This allows clients to create new filter lists and then associate them with other filter lists to create complex filters. This patch also has some minor bug fixes to AppliedFilterList so the new filters can be applied to existing NetworkPort instances. The new cimtests for the create/delete associations are still under construction, but you can easily test FilterList create/delete (foundation) with the following commands: # wbemcli ci 'http://localhost:5988/root/virt:KVM_FilterList.CreationClassName="",Name="",SystemCreationClassName="",SystemName=""' 'Name="test"' # wbemcli di 'http://localhost:5988/root/virt:KVM_FilterList.CreationClassName="KVM_FilterList",Name="test",SystemCreationClassName="KVM_HostSystem",SystemName="oc0840652111.ibm.com"' Signed-off-by: Chip Vincent <cvincent(a)us.ibm.com> diff --git a/libxkutil/acl_parsing.c b/libxkutil/acl_parsing.c --- a/libxkutil/acl_parsing.c +++ b/libxkutil/acl_parsing.c @@ -551,6 +551,57 @@ #endif } +int create_filter(virConnectPtr conn, struct acl_filter *filter) +{ + virNWFilterPtr vfilter = NULL;

[PATCH] Add read-only support

by Eduardo Lima (Etrunko)

# HG changeset patch # User Eduardo Lima (Etrunko) <eblima(a)br.ibm.com> # Date 1308270993 14400 # Node ID 9be9d0b2eed352a96bd07dcff435b8de5f7a43c6 # Parent a2f523cd39c29977ed07247a38316d44f5123874 Add read-only support. This patch enables a consumer of libvirt-cim to put it in read-only mode by adding the key-value pair 'readonly=true' to libvirt-cim.conf. Also clean-up some extra whitespace in touched files.

[PATCH] Add write support for FilterList and NestedFilterList

by Chip Vincent

# HG changeset patch # User Chip Vincent <cvincent(a)us.ibm.com> # Date 1309213800 14400 # Node ID 03e3f95547078be19d8d22cac83ce38daf7510b9 # Parent 75411f53df02159c3fa6ce5810c9446579e3d66d Add write support for FilterList and NestedFilterList This allows clients to create new filter lists and then associate them with other filter lists to create complex filters. This patch also has some minor bug fixes to AppliedFilterList so the new filters can be applied to existing NetworkPort instances. The new cimtests for the create/delete associations are still under construction, but you can easily test FilterList create/delete (foundation) with the following commands: # wbemcli ci 'http://localhost:5988/root/virt:KVM_FilterList.CreationClassName="",Name="",SystemCreationClassName="",SystemName=""' 'Name="test"' # wbemcli di 'http://localhost:5988/root/virt:KVM_FilterList.CreationClassName="KVM_FilterList",Name="test",SystemCreationClassName="KVM_HostSystem",SystemName="oc0840652111.ibm.com"' Signed-off-by: Chip Vincent <cvincent(a)us.ibm.com> diff --git a/libxkutil/acl_parsing.c b/libxkutil/acl_parsing.c --- a/libxkutil/acl_parsing.c +++ b/libxkutil/acl_parsing.c @@ -551,6 +551,57 @@ #endif } +int create_filter(virConnectPtr conn, struct acl_filter *filter) +{ + virNWFilterPtr vfilter = NULL;

[PATCH] (#2) Fix MemoryPool.Reserved to show only actively allocated memory

by Chip Vincent

# HG changeset patch # User Chip Vincent <cvincent(a)us.ibm.com> # Date 1308756569 14400 # Node ID c5a9510b6bd1569c6ab0966624306e29ecd81727 # Parent 6c29c5b284443e226e7d97e7e5f11848b0c4e761 (#2) Fix MemoryPool.Reserved to show only actively allocated memory. It appears Reserved is meant to show memory that is taken (actively in use by VMs) as opposed to memory that is potentially taken (assigned to defined, but not running VMs). Also added CurrentlyConsumedResource (a much clearer name for the same thing) and ConsumedResourceUnits, fixed units to conform with DSP1045, and cleaned up some extraneous whitespace.
