embden | Hello, I was reading the third task here: https://wiki.linuxfoundation.org/gsoc/2019-gsoc-agl and I have a question : what is meant by "partitioning hypervisor 'jailhouse'"? | 09:11 |

AlisonChaiken | embden, are your familiars with hypervisors like Xen or KVM? jailhouse is an alternative to them. | 18:39 |
embden | AlisonChaiken: I thought that Jailhouse is a concept that can be implemented via hypervisors. | 18:45 |
AlisonChaiken | Jailhouse is a kind of hypervisor. It replaces KVM or Xen. | 18:46 |
AlisonChaiken | I recall that there have been talks at Embedded Linux Conference about it. You should be able to find the slides and the video. | 18:47 |
embden | AlisonChaiken: is it like a L4 but Linux only? | 18:57 |
AlisonChaiken | Hmm. You'd be better off reading the LWN article, the _Linux Journal_ article, or watching the vid than asking me! | 18:58 |
AlisonChaiken | There is a ton of info about it. | 18:58 |
embden | AlisonChaiken: thanks, it is just wierd to call something "Jailhouse". Try to look for it in Google - learn more about prisons! | 19:00 |
AlisonChaiken | If you search for "Jailhouse hypervisor slides" you'll be on the right track. | 19:01 |
AlisonChaiken | If you add "site:lwn.net" or "site:linuxfoundation.org" then there will be no prison hits. | 19:02 |
embden | AlisonChaiken: I mean it's hard to find a comparison not with Xen but with the same class players like seL4. | 19:04 |
AlisonChaiken | seL4 is 'formally verified'. It is in a class all by itself. Jailhouse has a reputation for being less featureful but correspondingly less complex (which usually means less buggy). | 19:05 |
AlisonChaiken | That's about all I know about it. KVM is the only hypervisor I've actually used. Oh, and Green Hills. | 19:06 |
embden | AlisonChaiken: but there is a whole family of L4 hypervisors. Anyway, that's not what I want to do during GSoC - Zephyr+Jailhouse, thanks for your help! | 19:07 |
