Chainloading linux in AWS EC2 HVM

Thanks for the quick response!

Yes, the system log shows that xen_netfront and xen_blockfront are loaded.

Code:

[    5.808330] xen_netfront: Initialising Xen virtual ethernet driver
::::::
[    5.881939] blkfront: xvda: barrier or flush: disabled; persistent grants: disabled; indirect descriptors: enabled;
[    5.884958]  xvda: xvda3 xvda4

Also, the same CoreOS example provided in the previous post works on SoYouStart using their release of iPXE but not using the latest one I compile myself.

Edit1: Exactly the same problem. iPXE loads as expected and finds the kernel and initrd from the boot server.

Code:

I tried force loading netfront driver by adding

Code:

rd.driver.pre=xen_netfront,xennet,netfront

but the problem is the same.

Edit1: I did but didn't get it yet. Apparently they only patch the code to avoid replying to ping requests.
