From VMware to XCP-ng

[jasonnix]

Hi @planedrop,
1- Can XCP-ng communicate with storage devices like QNAP or EMC?

2- Is Xen Hypervisor more secure than VMkernel?

3- In VMware, it is possible to create complex networks with vSwitch. Is XCP-ng capable of such things?

[jasonnix]

Hi @jbamford,
So XCP-ng does not currently have some features like vSAN!

[jbamford]

@jasonnix Yes XCP-ng has vSAN look here https://xcp-ng.org/docs/storage.html#storage-types it is called XOSAN.

XCP-ng will work fine with EMC & QNAP. I am using two EMC iSCSI SANs with my 3 node Cluster.

@jasonnix On top of this it can also utilise the NFS and SMB protocols. You can thus choose from iSCSI, NFS or SMB which ever is right for the migration deployment.

@jasonnix

1. Yes, it can connect to many different kinds of network storage devices, just depends on how the share is exposed, but it'll do NFS, iSCSI, and SMB.

2. I would say so, I'm not some security expert (at least not at a programming/evaluating hypervisor level) but it's certainly a simpler system.

3. Well, depends how complex you are asking, there is virtual networking within XCP-ng.

Hi @planedrop,
Thanks again.
Is there somewhere that compares Xen with VMkernel? I want to convince my friend to use XCP-ng.

You're just trolling now, right?

@DustinB, Not really.

May I suggest you read a few different articles comparing the two then.

@DustinB, KVM is not VMware. The VMkernel is the name of the VMware hypervisor.

Fair enough, how about you perform some comparisons of your own, and explain the differences found by using the Xen kernel vs the ESXi Kernel.

Best of luck.

PS, Xen is not XCP-ng, just to confirm you understand the difference.

[jasonnix]

Thanks @DustinB. The XCP-ng using Xen hypervisor.

Thanks @DustinB. The XCP-ng using Xen hypervisor.

XCP-ng uses the Xen kernel, and its own tool stack to administer it.

XCP-ng is not "XEN" as much as a Honda and Toyota aren't the same cars, even if they use the same parts.

[jasonnix]

Sure @DustinB.
