KVM Snapshot for backup

Hi All, Has anyone experienced the virsh snapshot-create-as command on a KVM based instance? I am facing some blockers, and I cannot find workarounds. 1/ create a KVM instance from template ð Qemu chain is 2 nodes (1/ template, 2/ instance) 2/ make a snapshot (live) ð Qemu chain is 3 nodes (

Alright, hm. Before when I used to use bare qemu + VMM, I followed this: https://wiki.hetzner.de/index.php/Netzkonfiguration_CentOS/en#Routed_.28brouter.29 as linked to me by the DC. It should be possible to accomplish this in CloudStack right? On Sun, Aug 19, 2018 at 10:20 PM Ivan Kudryavtsev wr

It depends on how to implement guest networking. E.g. You can use vxlan for L2 over L3. Some designs are possible even with one zone, pid, cluster. вс, 19 авг. 2018 г., 23:34 Sagnik Sasmal : > Does that mean each host will reside in its own Cluster, Pod and Zone? > > On Sun, Aug 19, 2018 at 9:24

Hi. You can do that. No real reason to use LAN, just ensure that the connection between hosts and management is good. Also, it seems you have to deploy secondary storage on Swift/S3 rather than NFS. вс, 19 авг. 2018 г., 21:44 Sagnik Sasmal : > Suppose I want to deploy Cloudstack on hosts that hav

Questions regarding deploying servers that don't have any internal networking

2018-08-19 Thread Sagnik Sasmal
Suppose I want to deploy Cloudstack on hosts that have no correlation with each other and no private internal networking between them. Is there any way to go about this rather than creating individual Zones and Pods for each host?

Yeah, I was confused about whether there's a concept of like System Datastores and Image Datstores here. On Sun, Aug 19, 2018 at 5:18 PM Ivan Kudryavtsev wrote: > Hi. Snapshots, templates and isos are stored on secondary storage. All > these questions are described in docs, btw. > > вс, 19 авг.

Another one question: Are the VM templates and ISOs stored only on the management server and copied over when needed to the host, or is it possible to store them separately in both the management server and the host? On Sun, Aug 19, 2018, 5:01 PM Sagnik Sasmal wrote: > Thanks a lot :) > > On Su

I'm a bit confused about this. How should I make the partitions? Also, are LVMs (not shared, just local to the host), supported? A link to the docs would be great :) Thanks
