Re: [libvirt] [PATCH] esx: Restrict vpx:// to handle a single host in a vCenter

Now a vpx:// connection has an explicitly specified host. This allows to enabled several functions for a vpx:// connection again, like host UUID, hostname, general node info, max vCPU count, free memory, migration and defining new domains. Lookup datacenter, compute resource, resource pool and host system once and cache them. This simplifies the rest of the code and reduces overall HTTP(S) traffic a bit. esx:// and vpx:// can be mixed freely for a migration. Ensure that migration source and destination refer to the same vCenter. Also directly encode the resource pool and host system object IDs into the migration URI in the prepare function. Then directly build managed object references in the perform function instead of re-looking up already known information. --- docs/drvesx.html.in | 33 +++- src/esx/esx_driver.c | 360 ++++++++++---------------- src/esx/esx_storage_driver.c | 24 +-- src/esx/esx_vi.c | 588 ++++++++++++++++++++++++++---------------- src/esx/esx_vi.h | 26 ++- src/esx/esx_vmx.c | 4 + 6 files changed, 561 insertions(+), 474 deletions(-)
