I made a very first lab with vSRX which ova was downloaded from https://www.juniper.net/us/en/dm/free-vsrx-trial/
By using VritualBox and GNS3, when I started vSRX, the GRUB loading was hang forever as below picture.
I learned from Internet that adjusting memory to at least 6GB and 2 CPUs may help but it's still unsuccessful.
Hope to get your assistance.
Thank you very much
There are some setup notes and a juniper setup video linked in this earlier discussion.
You need to change the default import to free BSD and use the virtio interface type.
After modifying the options, I got another error. It went to Shell> if I chose boot order as below.
I tried studying its boot process but not very clear. I look forward to getting your ida.
I'm don't know. But would try using the alternative network drivers and see if that allows it to complete the boot.
