Re: [zones-discuss] Solaris 8/9 Container performance
I believe it may led to better performance, as the actual kernel (S10) is more efficient in many ways, while the overhead of adaption (ie. the brandZ code) is usually small.

Having a different date/time settings for non-global zones seems to be a commonly requested feature... IMO, it should be possible to allow a time offset in each non-global zone, but gettimeofday() time() in those zones will need to be modified to add the offset into the return value.

Other solution I think about is just to design containers without implementation, so I would not need any hardware. But unfortunately I do not have administration experience to decide about resource allocation.

Re: [zones-discuss] Any plans for a Vmotion-like Zone migration tool?
On 3/20/07, Nils Nieuwejaar [EMAIL PROTECTED] wrote: When migrating a zone, you would have to find some way to extricate the kernel state for just that some subset of a system's processes, devices, network connections, etc. - then insert that state into the middle of a kernel already running on another machine. To put it mildly, that would be hard. It's called kernel-level checkpointing... some operating systems (Cray unicos, IRIX) support it. It's hard, but doable. Those OS writes the address space of the processes to disk, and also record the system state related to those processes (pid, pgid..., IPC, sockets, etc). On restart, the kernel tries to allocate the resources, and resume the process(es). Restart can fail if the pid is already used by another process, for example. IMO, it's useful for long running applications (that's why those HPC systems have it), but for business applications, HA/clustering can do a better job.

Re: [zones-discuss] Re: [sysadmin-discuss] NFS server in zones
Hi all, Have we decided what to do for supporting NFS server in non-global zones?? And if we are going forward with the kernel approach (instead of running user-space NFS servers), then may be the NFS developers can answer a few questions: 1) How big a project is it?? (just a rough est) 2) Where is the code for the NFS service?? Which source directory(s) is the starting point?? Correct me if I am wrong - what we need to do to let non-global zones be NFS server is to change some of the data structures in the NFS server code to per-zone data structure - similar to IP Instances: ... take all the other data and convert it from global data to fields in an instance data structure page 21: http://www.opensolaris.org/os/project/crossbow/Docs/ipinstances-sug1.pdf And, if this is not many months of work, then sounds like it can be a summer of code project, and I will write up an initial project proposal (similar to what I am going to do for lx brand on SPARC (Project BrandZ) ): http://mail.opensolaris.org/pipermail/summerofcode/2007-March/11.html Rayson On 2/14/07, Octave Orgeron [EMAIL PROTECTED] wrote: Hi Tom, Thanks for the input.

I know one of my first bugs filed against the betas of Solaris 10 was the lack of NFS server functionality within zones. I've even been in the situation at work where this has been a requirement, only to have to scrap projects. Probably the most common idea for having a zone NFS server is for Jumpstart or home directories. As things stand today, it's not doable. I've even escalated this thru different channels over the past few years only to see it go no where. I'm sure there is a lot of demand for this feature for zones. I think the key requirements would be: 1. Full NFS server functionality within a zone. So things like share, /etc/dfs/dfstab, sharemgr, ZFS sharing, etc. should work in the same manner as they do in the global zone. 2. Security. Separation of NFS namespace to insure proper security between zones. This may be achieved by making the kernel NFS framework aware of the zoneid context. 3. Performance. NFS serving out of a zone should not be slower or less scalable than NFS serving from the global zone. Starting a project would be nice. But I think there should be close involvement with the NFS engineers at Sun. As for getting their attention and funding, the best we can do is show enough community interest for NFS within zones. So I'd ask all sysadmins, developers, etc. to respond to this thread to show support for fixing this. Octave, Thanks for the input on the requirements. I am a NFS engineer for Sun. I don't think we should count on getting attention and funding for Sun's NFS engineers to do this project. All of us are aware of the need, but are focused on delivering other products. I'm not saying they will not help out, I don't think you could stop them. Again, I think that this is a golden opportunity to start an OpenSolaris project in the clear and with full involvement from the community. I'm willing to provide project leadership and mentoring to external developers. I'm pretty sure that the other NFS engineers are willing to review requirements, specs, design, code, etc. But the bulk of that work will fall on the community to provide. I'm not looking to start a project which gets done entirely within Sun. Thanks, Tom ___ zones-discuss mailing list zones-discuss@opensolaris.org
Re: [zones-discuss] guidance for beginner
On 2/3/07, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: I can avoid giving root access to the users with sudo. But does that mean giving them zones will be easier or safer? Yes, giving away root access in non-global zones is very safe. There is no way to escape from a non-global zone to another non-global zone or to the global zone. So even the root user can only modify settings in his own zone.
