Fix PCI device attach in xend driver
|
|
|
|
When attaching PCI device using the xend driver, the 'device_create'
|
|
RPC is called, which is not sufficient to fully prepare/configure
|
|
the device for attachment to a domain. In the xen tools, xm pci-attach
|
|
uses the 'device_configure' RPC.
|
|
|
|
This patch changes the xend driver to always call 'device_configure' for
|
|
PCI devices to be consistent with the usage in the xen tools.
