AW: XenServer Licensing Change - Switch Hypervisors?

2018-02-03 Thread S . Brüseke - proIO GmbH 
No concern at all, just a lack of knowledge on my side. ;-) How do you mount 
the shared ScaleIO volume on the KVM host? Do you just mount it and use a 
cluster filesystem on it?

We too was evaluating ScaleIO on XS, now we move to KVM or Hyper-V but always 
with ScaleIO, I don't understand your concern about ScaleIO on KVM.

Hi Alessandro,

we are in the same situation with using XenServer 6.5. Besides it will not be 
patched XS6.5 has poor memory performance. We are in the middle of evaluating 
KVM with ScaleIO to get rid of XenServer in the near future. I am stuck right 
now on how to mount a ScaleIO volume do a KVM host.
Migrate all VMs will be a pain in the ass, but XenServer is not the way to go 
after all the decisions Citrix did in the past with its hypervisor.

We are more Linux related so Hyper-V is not an option for us and as far as I 
know you cannot mix Hyper-V with other hypervisors in the same zone in 
Cloudstack. But I am not sure if this limitation is still present in the latest 
stable release.

Hi all,
I'm also trying to find a solution, our infrastructure is based on XS6.5 that 
will not patched on meltdown and spectre so we're considering to create new 
cluster based on a different hypervisor instead of upgrade to XS7.2.
In fact, I think that all here work for a company that has a MS SPLA agreement 
in place, so my question is: since we're already paying MS Datacenter license, 
what do you think about Hyper-V under Cloudstack?
I'm trying to compare it versus KVM...


Thank you.

Hi Alessandro,

we are in the same situation with using XenServer 6.5. Besides it will not be 
patched XS6.5 has poor memory performance. We are in the middle of evaluating 
KVM with ScaleIO to get rid of XenServer in the near future. I am stuck right 
now on how to mount a ScaleIO volume do a KVM host.
Migrate all VMs will be a pain in the ass, but XenServer is not the way to go 
after all the decisions Citrix did in the past with its hypervisor.

We are more Linux related so Hyper-V is not an option for us and as far as I 
know you cannot mix Hyper-V with other hypervisors in the same zone in 
Cloudstack. But I am not sure if this limitation is still present in the latest 
stable release.
