[libvirt-users] BIOS Delay

[xuteng]

Hi,Eric:
Thank you for your reply.
All I want to do is like this:
I have 2 vms ,vm-01 and vm-02 which set to be autostart both.
further more, I want vm-02 start 10sec later than vm-01.
Compared with VMware ESX which has a function that can delay several times after the vm run into bios,
Does libvirt also have some fuction like this or should I write a shell script to controll the start pace of the vms ?

Is there a qemu option that affects this?  I'm not aware of one, off the 
top of my head, which means that libvirt does not expose one directly. 
If there _is_ such a qemu option, then you can access it via 
<qemu:commandline> xml while waiting for libvirt to implement official 
xml to support this feature.

Taking a step back, I'm not even sure what you are trying to accomplish 
with a delay.  Perhaps it is sufficient if you use virDomainStartFlags 
with VIR_DOMAIN_START_PAUSED (or virsh start --paused) to request that a 
guest be created without running it, then at your choice of delay, 
resume the guest?  But that's not a BIOS delay.
