From 23247a1efd9ab41204e434aaf6798b7f807c4c31 Mon Sep 17 00:00:00 2001 From: Matthias Bolte Date: Tue, 1 Nov 2011 17:12:37 +0100 Subject: [PATCH] esx: Support folders in the path of vpx:// connection URIs Allow the datacenter and compute resource parts of the path to be prefixed with folders. Therefore, the way the path is parsed has changed. Before, it was split in 2 or 3 items and the items' meanings were determined by their positions. Now the path can have 2 or more items and the the vCenter server is asked whether a folder, datacenter of compute resource with the specified name exists at the current hierarchy level. Before the datacenter and compute resource lookup automatically traversed folders during lookup. This is logic got removed and folders have to be specified explicitly. The proper datacenter path including folders is now used when accessing a datastore over HTTPS. This makes virsh dumpxml and define work for datacenters in folders. https://bugzilla.redhat.com/show_bug.cgi?id=732676 --- docs/drvesx.html.in | 10 +- src/esx/esx_driver.c | 30 ++-- src/esx/esx_util.c | 22 +-- src/esx/esx_util.h | 4 +- src/esx/esx_vi.c | 267 +++++++++++++++++++++++++++++---- src/esx/esx_vi.h | 11 +- src/esx/esx_vi_generator.input | 4 + 7 files changed, 280 insertions(+), 68 deletions(-) diff --git a/docs/drvesx.html.in b/docs/drvesx.html.in index da9d2a1ba7..7d323b3521 100644 --- a/docs/drvesx.html.in +++ b/docs/drvesx.html.in @@ -56,7 +56,7 @@ esx://example-esx.com/?no_verify=1 (ESX over HTTPS, but doesn't verify the s URIs have this general form ([...] marks an optional part).
