[libvirt] [PATCH 1/2] virsh: Add options for several commands which change domain config
Osier Yang

Tue Jun 21 05:37:31 UTC 2011
All of the following 7 commands just provide one option (--persistent)
for user to specify how to affect the domain:
attach-device
detach-device
attach-disk
detach-disk
attach-interface
detach-interface
update-device
However, All of the APIs the above 7 commands use: virDomainAttachDeviceFlags,
virDomainDetachDeviceFlags, and virDomainUpdateDeviceFlags support following
3 flags:
VIR_DOMAIN_AFFECT_CURRENT
VIR_DOMAIN_AFFECT_CONFIG
VIR_DOMAIN_AFFECT_LIVE
This patch add two new options (--live, --current), and changes
"--persistent" into "--config", just as other similar commands,
e.g. "schedinfo", "vcpupin".
And since the APIs are designed as: If no flag is specified, behaviour
is different depending on hypervisor, so virsh shouldn't do things like:
if (virDomainIsActive(dom) == 1)
flags |= VIR_DOMAIN_AFFECT_LIVE;
This patch removes codes like this, leave the determination for underly
hypervisor driver.
