[libvirt] [PATCH] Power Hypervisor now with libssh2

Hello friends, This is the new version of phyp driver now using libssh2. I also did some other changes: * Added some debug information. Sometimes its worth to know which command is being executed and where. So I added the PHYP_CMD_DEBUG macro. * All the connection startup is now "hard coded" in libssh2. For example, I need to open the socket and start the connection all by myself. Not a big deal, but in a near future I am planning to send a patch to libssh2 to encapsulate all these procedures into functions, hence, less code, probably less bugs :) * There is a lot of "out of scope" functions in the bottom of the file. In the next patch I may put all those together in a phyp_config.[ch] in order to get things clearer. What's up next: * The problem of handling the UUID in a centralized way still remains. I started to handle this by opening a sftp connection to the HMC system and transfer my UUID database. But there is an odd behavior that makes the driver connect OR NOT to some HMC systems. * CPU management: this feature planned to be released in this version is not ready yet due to the issue above. * Storage management. Vacations: I'll be on vacations from 26th/august to 14th/september. I'll check my emails in the meanwhile, but no so often. Anyway, any comments on this patch are always welcome :) []'s -- Eduardo Otubo Software Engineer Linux Technology Center IBM Systems & Technology Group Mobile: +55 19 8135 0885 otubo(a)linux.vnet.ibm.com
