To: Adrian Chadd Here is the note Problem: QCOW2 can cause corruption under some stress conditions. Solution: Consider using RAW disk image.As such, the default for Kimchi is to also use RAW disk image format. It is on the Power Linux Wiki https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/W51a7ffcf4dfd_4b40_9d82_446ebc23c550/page/IBM%20PowerKVM%202.1.1%20Known%20Issues%20and%20Readme On Jan 5, 2015, at 11:22, Adrian Chadd wrote: hi!

So, we got the basics booting on the hypervisor but nathan hit a roadblock with the virtualised storage layer getting garbage. It works on the emulators, but not on the qemu-kvm setup that the hypervisor platform uses. He got a bootloader working on bare metal and the kernel loaded enough to printf("hello, world") right at the beginning out the serial port. He wrote a kexec bootloader that will suck in FreeBSD and call kexec to boot it. He was using a PS3 to debug it, as the PS3 already runs FreeBSD and it also uses an embedded Linux as a bootloader that uses kexec. :) So, progress. There's apparently a whole bunch of infrastructure code that needs writing before we can speak to the rest of the device tree on the metal. But now that we have the basics up and running the progress should be nice and quick. (God it's loud!) -adrian On 4 January 2015 at 12:38, Steven Peterson wrote: How goes the hackathon?

We need some more bootloader support before we can boot - apparently the firmware for these things uses linux and it kexec's a new kernel to boot. So we need support for that framework. Nathan is working on that this week. Ok, so for the serial ports, what kind of serial ports are they? I'm likely going to have to acquire DB9/DB25 hardware to match.. :) -adrian --f46d044403b2d0f70d050beb8fbe Content-Type: application/pgp-signature; name="signature.asc" Content-Disposition: attachment; filename="signature.asc" Content-Transfer-Encoding: base64 X-Attachment-Id: 9855613e2ba7ac7b_0.1 LS0tLS1CRUdJTiBQR1AgU0lHTkFUVVJFLS0tLS0NCkNvbW1lbnQ6IEdQR1Rvb2xzIC0gaHR0cDov L2dwZ3Rvb2xzLm9yZw0KDQppUUljQkFFQkFnQUdCUUpVcXNnR0FBb0pFUEh2RlFGUCs3cGgvdkFQ L0ErS2h6VmlYUTVyRWMzT0o2Sm8rVUdQDQoyRHdBZk83VXdYQm9RU0RraVV1QUpxYnMrNWU5RkZ1 RkF3SStaL0lTQ2tmYVlaQlczWDVlejltdDZkTmpxWFBCDQpGMGlwT0JsRnhwSGp2cTFsdkw1TU01 T29qVlRKdkdPTDQyL3RJNGFHSEdnc2FLa0VtSW03aWhmaUtaUzV5YzF1DQpsV3ozOXJXbHpTRFBE b01vVGpzb3djTVFkT09UYXgxazhxRHA4TVA2MW1OK2ZtYlNTeUwvbWVpdFFMeGlzRysrDQozdkQv SVloRndxWWpSeWtuekMwTTVNOUdWWFlOeEp5R25HMzJVSUZWVmVnVGQ1RWQ3Q28reStJYldQcXBn b1MrDQpXMVFEeGlGUk5zOUtpSGxlb292OTVyRitqQUMvYU9UMUo0ektqVEtzYk1DcFZPNTRyNVRp MEd0MmhnMjVJdE45DQpTZ25IYksrNnA2NzVacEVPbVczOGZqOVhXbm9wbVExdlBaVzBNcXZLd3lo QUZLNCswc0pYNkF0ZXdoUlpXNzFyDQp6TitSQXAwRHpOOVl2V3Y2OEc0djJyVkhsWXB2LzdBeVNZ cWNQc09CY2FkV0NZc3ZwalNTR2NzSWNqR0hRWnlnDQpEYVJXYk5MNVd3TEd5aU53ZEI0RFVHVEJY eTUwRnpDM3BFcXExWVI3R3FJZkFOTlM5ZnVvdEl0K0ViMml2dXVRDQpLSlJKSUVrTUluRGxmWnd4 dHRNeGhPWVJrSEw3TUpHd3IvNGJsejArMXF3SjdHMk4rb1JCLy9vd1FYYW1UbS9tDQpkbjdRK2J5 em8yc244a3FwQmFrY1pOa2dUekxrMkJiS1lGK2RUNnllMCtCTWphU2RrZzM1eFRUeFpUeHlxMElV DQpQdDgrNVd2NUNza2owOGlKR2FXUQ0KPU9oQzkNCi0tLS0tRU5EIFBHUCBTSUdOQVRVUkUtLS0t LQ0K --f46d044403b2d0f70d050beb8fbe--
