loadvm for arm vexpress-a9
Description of problem:

Steps to reproduce:
1. savevm test
2. loadvm test
3. After I execute savevm and loadvm,the guest is not responding
Additional information:
I have read this issue(https://github.com/panda-re/panda/issues/643). If secure is set to off,the guest works well. But I need to use  security extensions,so secure cannot be set to off.What do I need to do  to solve this problem？
