I have hit a problem running libvirt based containers in a CentOS 7 based host, with the extra wrinkle that my host is an EC2 instance in AWS. Ultimately everything works as advertised, and I can launch instances that host multiple libvirt lxc containers without problems, with one caveat: About one time in ten when the containers are started, the instance loses all network connectivity. This

Hi I plan to host Asterisk instances on AWS/EC2 servers. Requirement is to run asterisk instance with transcoding (g.729 + g.711) and full recording. Number of concurrent calls expected are 500+. 2 instances will be configured for 100% redundancy. Heart beat will be used to determine active instance. How should I choose EC2 instance? How many vCPU, RAM should be selected? I am assuming that

Hi Jeff Are you aware of any challenges of hosting it on AWS? It will help me to work out alternate plan. Is there any recommendation? Should I split it to multiple instances and balance traffic across multiple small server instances? I can use Kamailio to balance traffic. I see many posts referring to AWS deployment. Please help me to choose AWS server instance. *Thanks & Regards,*

Hello, I've got an AWS cloud and a local network. I'd like to setup an access from private EC2 instances to local network tinc server. There are two public EC2 instances with tinc server installed, other (private) EC2 nodes do not have tinc. http://imgur.com/tq84crc VPC subnet: 172.22/16 VPN subnet: 21.0.0/24 Source EC2 instance ip: 172.22.0.100 Tinc 1 ip: 172.22.0.101, 21.0.0.1 Tinc 2

We're transitioning from a VM based environment to one that uses LXC based containers running under CentOS 7. CTDB runs fine under our CentOS 7 VMs. The same packages running under LXC however seem to have issues: # systemctl start ctdb.service Job for ctdb.service failed. See 'systemctl status ctdb.service' and 'journalctl -xn' for details. # systemctl status ctdb.service

I'm using libvirt_lxc and that has an XML based configuration. Based on what I've read, I think I need to add this to the ctdb container's config: <features> <capabilities policy='default'> <sys_nice state='on'/> </capabilities> </features> That didn't do the trick though. I need to figure out how to turn on all caps to

Hi, Is there a way to backup KVM Guest VM running CentOS Linux release 7.9.2009 (Core) OS in kvmguestosimage.ova or kvmguestosimage.vmdk format as I am trying to restore it in AWS by referring to https://aws.amazon.com/ec2/vm-import/ article as per the below supported file format. [1] Open Virtualization Archive (OVA) [2] Virtual Machine Disk (VMDK) [3] Virtual Hard Disk (VHD/VHDX) [4] raw Also

I''ve seen a couple of examples of using puppet to control services where you can''t run a puppet agent on the resource. As far as I can tell they work by having puppet proxy through some external-service control mechanism, such as fog. The question is: where does the proxy run? I assume a puppet agent needs to run somewhere. Where do you put that agent, how do you configure it,

Hi All, I was wondering if anybody had experience running R on amazon's ec2 "cloud"? More specifically, has anybody created an "amazon machine image" (AMI) for use with it? I was wondering if there was a quantian type image available as an amazon machine image, maybe running debian or ubuntu? It supports open MPI among other libs which is nice. It would be nice to put
