Failed to create a domain with xen-unstable (Error 22: Invalid argument)

Failed to create a domain with xen-unstable (Error 22: Invalid argument)

[Jun Koi]

Hi,

The latest Xen unstable fails to create a HVM domain for me, with
Error 22: Invalid argument. Below is part of the logging info.
Is this a bug introduced recently, or did we change the config file format??

Thanks,
J

hi,all

As one of the new feature of xen-4.0-rc1, there will be 128 vcpus. My
question is that can these vcpus be put in one hvm? That is, can I
create a virtual machine containing 128 cpus?

RE: Failed to create a domain with xen-unstable (Error 22: Invalid argument)

[Xu, Dongxiao]

Yes, one VM could own maxium 128 vcpus.
The failure you meet should be a regression. I am looking into it. 

Thanks!

Thanks! Let me know if you need more information.

Anyway, I am wondering how a simple bug like this can evade the
auto-testing process??
