I was really hoping you would talk about XOSAN v1 or v2. It's always mentioned in the documentation, but I have never seen it in action. Perhaps XOSAN is just a Hoax?
@@marco114 most of the other features are not open source i.e proxies, but I have seen them either in the 30 days trial vm or in other videos/demos. XOSAN to me is just a myth at this point.
@@bentleymax2511 XOSAN was a Third Party solution for XenServer (NOT XCP-ng) and V2 (which should support XCP-ng) isn't finished yet, and will probably be replaced by whatever comes out of their collaboration with Linstor
THANK YOU for the XCP-specific storage instruction. IF you ever get a chance to talk about CEPH storage; I would really love to see a video on that as well. Your channel is priceless!
Fixing to setup my first xcp-ng server with local storage, so perfect timing. Also is the any updates to building xcp-ng from source since your last video?
It's not hypervisor/Xen related, it's toolstack related. When you live migrate a disk from one SR to another, it works like this under the hood: 1. A snapshot is created for the disk 2. A disk mirror is started on destination (all new blocks after the snap are mirrored on destination disk) 3. Then, the whole snapshot (all blocks) is copied to the destination storage (this takes most of the time) 4. When it's copied, the VM is briefly paused (like during a normal live migration, it's barely visible) to switch to the destination disk 5. If it worked, then the source disk is removed, and voila! That's a very similar mechanism when you live migrate a VM from a pool to another (sharing nothing), you can add memory migration in step 4. Note: it's fully transparent from the VM perspective, no need to get any special configuration. Neat, isn't it? Source is XAPI doc, here: xapi-project.github.io/features/XSM/XSM.html
I watched this video and I still can't migrate my VM to another host. I have two xcp-ng hosts running and VM'S running in each host but when I try to migrate one to the other host, it shows it's migrating and takes a while, then when it stops it's still on the same host. It does not move to the other host. Both host are connected to my network and are available in xen orchestra, do I need to configure a static IP on another network port on each server (host) or any suggestions? Thanks!
@@LAWRENCESYSTEMS Same network segment, not sure if it times out but it does not give an error, when check pools there are two host, both say Master. So I guess it's two separate pools. it's two servers. I will join the forum and post. Thank you.
how does incremental snapshots work in xc-png , there is i think a capacity of 20 snapshots in total after that how are we supposed to proceed . can i have an api for that ? what is the logic behind .
@@LAWRENCESYSTEMS Makes sense. If the HA-lizard project matures and gets integrated, it might turn XCP-NG into an hyperconvergence solution (like Nutanix)...right?
I've tried asking in XCP-ng forums but have yet to receive an answer so hopefully you can answer this question. What are the requirements for a Suspend SR? I would like to be able to take snapshots with VM memory but I don't know if I can simply set my primary SR to also be a Suspend SR or not. Last I looked there was nothing in their forums or docs explaining how to configure it.
@@LAWRENCESYSTEMS Thank you! Set my primary SR as a Suspend SR and snapshot with memory worked perfectly! I was worried setting that on my primary SR could potentially cause issues (worst being VM lockups or vdi corruption) so I'm glad that didn't happen.
