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

<DIV>> Hi,</DIV>
<DIV>> Does the libvirt support the bios delay ?</DIV>
<DIV>> I mean that after set a special number of seconds or minutes, when the domain starts, the bios will delay after the time I set</DIV>
<DIV> </DIV>
<DIV>Is there a qemu option that affects this? I'm not aware of one, off the </DIV>
<DIV>top of my head, which means that libvirt does not expose one directly. </DIV>
<DIV>If there _is_ such a qemu option, then you can access it via </DIV>
<DIV><qemu:commandline> xml while waiting for libvirt to implement official </DIV>
<DIV>xml to support this feature.</DIV>
<DIV> </DIV>
<DIV>Taking a step back, I'm not even sure what you are trying to accomplish </DIV>
<DIV>with a delay. Perhaps it is sufficient if you use virDomainStartFlags </DIV>
<DIV>with VIR_DOMAIN_START_PAUSED (or virsh start --paused) to request that a </DIV>
<DIV>guest be created without running it, then at your choice of delay, </DIV>
<DIV>resume the guest? But that's not a BIOS delay.</DIV>
