Re: Issue after creating snapshot

Did you check the hierarchy of these files with 50KB?

I believe that when ACS takes a snapshots it will create a hierarchy of 
VHDs, and since you are looking for the leaf right after the snapshot, 
it is for sure empty (or almost empty)

Re: Re[2]: Oracle VM 3.4 with ACS

Posted by Dag Sonstebo <Da...@shapeblue.com>.
Hi David,

Apologies – wrong wording on my part – Oracle VM is supported, but this hasn’t been maintained in CloudStack for quite a few versions now. We did a brief test of it 6 months back and found it will need some development work to get it back on track.

Hope this clarifies things.

Thanks Dag for your quick response. Reading the official documention from https://cloudstack.apache.org, i found out ACS supports Oracle VM



CloudStack currently supports the most popular hypervisors: VMware, KVM, Citrix XenServer, Xen Cloud Platform (XCP), Oracle VM server and Microsoft Hyper-V.



Dag, why is not supported from your point of view? Did you try it?



Thanks for your feedback

Hi David,

Oracle VM isn’t a supported hypervisor in ACS unfortunately, not aware of any work having been done on this – but someone else may know.

Hi all, our infraestructure is based on ACS 4.9.2 with XS 7. We need to deploy new host based on Oracle VM and we will have to set spinning CPU (1 socket per host) 




1./ Do you know if this configuration is compatible with ACS?




2./ I didn't find to much information about the "real" issues of Oracle VM & ACS. Is there any user working in a production environment with Oracle VM & ACS?

Re: Issue after creating snapshot

Posted by anil lakineni <an...@gmail.com>.
Hi Vivek,

Can you detach one of the data drive and try to power-on the VM, check if
it works for you in starting of VM. If so, re-attach the detached drive to
VM in online.

P.S.: I sometimes seeing this type of issue when the VM got up with more
than 4 drive which includes ROOT disk.


Thanks.
Anil.
