what a correct use for virConnectDomainEventRegisterAny API, how to Obtain a stable expected result
HI, everyone:
My target deal with network hotplug use virDomainDetachDeviceFlags. Because when the API return ,the network maybe doesn’t remove from my vm guest os.
So I use virConnectDomainEventRegisterAny to register an event ID: VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED ,
my process as follow:
cb_para->call_id=virConnectDomainEventRegisterAny(cb_para->conn,cb_para->do...

Detaching device behaviour
Hi all.
In libvirt documentation it is written that virDomainDetachDeviceFlags is
an asynchronous call:
http://libvirt.org/html/libvirt-libvirt-domain.html#virDomainDetachDeviceFlags
Does that mean that also virDomainDetachDevice is asynchronous? the reasons
mentioned in the above seems relevant for this one as well.
Thanks!

Qemu driver not supporting VIR_DOMAIN_DEVICE_MODIFY_CONFIG yet?
Hi,
According to the docs on
http://libvirt.org/html/libvirt-libvirt.html#virDomainDetachDeviceFlags
I ought to be able to do
virDomainDetachDeviceFlags(
<domain>,
<devicexml>,
VIR_DOMAIN_DEVICE_MODIFY_LIVE | VIR_DOMAIN_DEVICE_MODIFY_CONFIG);
to detach a volume both from a currently running VM instance and permanently
from the defined config file.
If I actually try that, though,...

when virEventAddTimeout trigger timeout ,should in the callback call virConnectDomainEventDeregisterAny ?
hi, all
I do a hotplug detach a network in a thread, because virDomainDetachDeviceFlags maybe asynchronous, so I do like follow:
cb_para->cluster_id = info->cluster_id;
cb_para->group_id = info->group_id;
cb_para->vsys_id = info->vsysid;
cb_para->vnf_id = info->vnf_id;
cb_para->conn = conn;
cb_para->time_out = 20*1000;//20s

Re: Detach disk from VM - virsh (working) vs. PHP (not working)
Thank you for your help!
1, i used vda as install disk and vdb as target disk, because i boot from the first. After setup boot order flag i was able change install disk to vdb and target disk to vda. With this configuration when i boot from vdb i can install OS with grub and after it redefine XML without vdb without problem. Thanks a lot.
2, maybe i have something wrong, but still not working:

Ah, of coure. I overlooked that virDomainDetachDeviceFlags() is called
with VIR_DOMAIN_AFFECT_CONFIG, which means that live configuration is
not affected and if the disk you're trying to detach exists only in live
XML then the API fails. The same problem was found in
libvirt_domain_disk_add, libvirt_domain_nic_add and
libvirt_domain_nic_remove.

why virConnectDomainEventRegisterAny can't alway trigger the callback ,how can i get a stable callback ?
...ctDomainEventRegisterAny(conn, dom, VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED, VIR_DOMAIN_EVENT_CALLBACK(vnf_control_del_network_cb), cb_para, vnf_control_del_network_cb_free);
flags |= VIR_DOMAIN_AFFECT_CONFIG;
if (virDomainIsActive(dom) == 1) {
flags |= VIR_DOMAIN_AFFECT_LIVE;
}
ret = virDomainDetachDeviceFlags(dom, xml, flags); // detach a nic from vm guest os
。。。。
}
void vnf_control_del_network_cb(virConnectPtr conn, virDomainPtr dom, const char *dev,void * opaque) //this callback can't already trigger to run ，why ?
{

[PATCH Fedora libguestfs] Don't depend on libvirt-daemon-kvm monolith.
libguestfs usually needs qemu. However it only requires an emulator
for the same architecture, not for all architectures.
libvirt-daemon-kvm pulls in qemu which pulls in emulators for all
architectures, as well as a bunch of other stuff we don't need at all
like network interface support and nwfilter.
There are no Fedora TCG-only arches, so drop the conditional section.

[PATCH v4 0/5] Finish hotplugging support.
This rounds off hotplugging support by allowing you to add and remove
drives at any stage (before and after launch).
