[et-mgmt-tools] [PATCH] check a UUID format

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

When I install by virt-intall with invalid UUID(e.g."--uuid=4096 Characters"),
virt-install freeze.

So, here's the patch adds to check a UUID with following format:
    xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx ( xx should be in hexadecimal )

Thanks,
