[libvirt-users] BIOS Delay

Hi, Does the libvirt support the bios delay ? 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 Thanks for your time wade xuteng via foxmail

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. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

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 ? xuteng via foxmail Sender: Eric Blake Date: 2011年10月12日 星期三 上午5:55 To: xuteng CC: libvirt-users Subject: Re: [libvirt-users] BIOS Delay On 10/10/2011 02:50 AM, xuteng wrote:
