<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hello,<br>
<br>
I am a new user to Panda, and I am reproducing the SSL/TLS key extraction experiment by following this tutorial:<br>
<a href="https://github.com/moyix/panda/blob/master/docs/panda_ssltut.md" target="_blank">https://github.com/moyix/panda/blob/master/docs/panda_ssltut.md</a><br>
<br>
I'm using Ubuntu 14.10 as the guest OS in QEMU. In the key searching phase, I got an assertion failure in kvm.c (see below). My recording was successfully made with KVM turned on (otherwise it was unacceptably slow).<br>
<br>
Thanks for help,<br>
