Can I use KVM local storage for user vm
*Hi,*
My setup is AlmaLinux8, all are working fine using mgmt+nfs, but I have
8 NVME disk (every disk size 1.8TB) mount on kvm server, so I want to
use all disk as user vm storage disk separately.
*My idea is :* When setup zone then using enable local storage. But this
settings is only for one disk or all kvm server disk.
But I have 8 disk, so how to trace mgmt server my all 8 disk separately.
For example, I want 5 user vm for disk 1, another 5 user vm use disk 2,
as like another user vm disk 3.......etc.
which process can I use this disk? give me some idea please ...

*Thanks & Regards.*

I don't exactly understand your question, but from the output you've given, the nvme disks have not been formatted and mounted on the paths you've supplied as /var/lib/libvirt/images*. Is the host you've shared this output of the same as your hypervisor, as in: your management-server and cloudstack-agent run on the same system? What version of ACS are you running?
Met vriendelijke groet / Kind regards,

Hi,
To control the volume placement to storage you can use storage tags.

Hi,
You can add kvm hosts with multiple local storages.
https://github.com/apache/cloudstack-documentation/pull/333/files
Each storage will be added as a storage pool.
You can deploy vms, migrate vms/volumes between pools.

Re: Can I use KVM local storage for user vm
Posted by Rohit Yadav <ro...@shapeblue.com>.
Hi,
It appears you've selected the host ID c26965e6-bf5f-482e-9cff-849174f6f476 when deploying the VM. Later in the logs it mentions:
2023-09-07 04:43:07,996 DEBUG [o.a.c.s.a.LocalStoragePoolAllocator] (API-Job-Executor-8:ctx-45334d86 job-14 ctx-c4c19ea4) (logid:28386839) LocalStoragePoolAllocator is returning null since the disk profile does not use local storage and bypassStorageTypeCheck is false.
And then:
No suitable pools found for volume: Vol[3|name=ROOT-3|vm=3|ROOT] under cluster: 1
...snipped...
Cannot deploy to specified host, returning.
Can you check if (a) you've local storage enabled for the zone and (b) there is local storage available from the selected host (you should see a local storage pool in CloudStack and it should mention a local storage uuid in the KVM host's /etc/cloudstack/agent/agent.properties).
If this is a test environment, you can attempt to setup again fresh.
Regards.

Re: Can I use KVM local storage for user vm
Posted by Wei ZHOU <us...@gmail.com>.
Hi,
You can add kvm hosts with multiple local storages.
https://github.com/apache/cloudstack-documentation/pull/333/files
Each storage will be added as a storage pool.
You can deploy vms, migrate vms/volumes between pools.
