segator Posted April 1, 2015 Share Posted April 1, 2015 Can I pass LVM to KVM? I don't want to use .img .qcow or .raw files. In virtualbox You can use a partition as disk VM Can I use the same in KVM + unraid? How I format a drive to apply LVM? Quote Link to comment

segator Posted April 7, 2015 Author Share Posted April 7, 2015 Solved, KVM support LVM passthru example < disk type='block' device='disk' > < source dev='/dev/vgpool/test'/ > you need to create manually the LVM struct from unraid The Drive is OUT of the array, SNAP plugin Not support LVM I think. Work well but performance it's not improved Quote Link to comment
peter_sm Posted November 25, 2015 Share Posted November 25, 2015 Any chance to see this in upcoming releases ? Quote Link to comment
jonp Posted November 26, 2015 Share Posted November 26, 2015 Any chance to see this in upcoming releases ? Meh, I played with LVM and was not impressed at all. Doubt we will include official support for it any time soon. If someone can prove / show a use case for it, we could consider working on it, but for now, it seems like a lot of work to test and maintain with very little real benefit. There are tons of things we COULD do with VM storage, but why should we when there are other areas needing much more attention. Quote Link to comment

My tests didn't show that and when multiple VMs are in an LVM, I don't think it scales very well. Plus, shouldn't you just buy an SSD? Quote Link to comment

Sorry, I was implying that SSD performance should be further up the list of 'things to do' than LVM support. Quote Link to comment
jonp Posted November 26, 2015 Share Posted November 26, 2015 Ok, then you are forgiven ;-). I agree Quote Link to comment
peter_sm Posted November 29, 2015 Share Posted November 29, 2015 I have now added my 2:nd SSD and use that as LVM volume, I used dd to migrate a exixting VM from my SSD-1 to the LVM on SSD-2 Question are how to do a performance test for these 2 VM ? root@Tower:~# lvscan ACTIVE '/dev/vm-disk/OSX' [90.00 GiB] inherit ACTIVE '/dev/vm-disk/Backup' [15.00 GiB] inherit root@Tower:~# pvdisplay --- Physical volume --- PV Name /dev/sdm1 VG Name vm-disk PV Size 119.24 GiB / not usable 3.34 MiB Allocatable yes PE Size 4.00 MiB Total PE 30525 Free PE 3645 Allocated PE 26880 PV UUID N8Mff2-kkCL-xoWi-wBil-8mw0-Iv5t-TLpDA8 //Peter Quote Link to comment
