Hi All. I have currently a small problem to solve. I have a kvm virtual machine which in output of ifconfig eth0 | egrep 'RX packets|TX packets' RX packets:792681304 errors:0 dropped:560728 overruns:0 frame:0 TX packets:716661674 errors:0 dropped:0 overruns:0 carrier:0 show dropped packets.

Hi all. We currently want to deploy a test private IaaS. It will look something like below: 2 Gb switches several hardware nodes for virtualization (?) 2 10Gb switches redundant storage (?) What are you proposing to use on every level? Eucalyptus/OpenStack/something else for cloud management? And why? KVM/Xen/something else for virtualization? iSCSI/NFS/something else for storage? Please

Hi All. I have two servers ("master" and "slave") with a replicated gluster volume. Recently I've had a problem with slave and gluster does not work on it now. So I would like to: - stop and remove current volume on master (on slave it is not accessible); - stop gluster software on master (already stopped on slave); - remove gluster software on master and slave (previous

Hi all. I am currently designing a server room. I would like to be able to draw a 2D (in the future 3D) project. Do you know any tools? Which one can you recommend? Best regards, Rafal Radecki.

Hi All. I want to use mentioned version of glusterfs in a simple master/slave setup (production servers). Two nodes have a replicated volume and the both mount it using glusterfs. What are your experiences with gluster 3.3? Is it stable? Have you had any serious problems? I do not have much experience with gluster and would like to avoid problems if possible. Best regards, Rafal Radecki.

Hi All. I have a setup in which I have two servers serving nfs share. The nfs service is made highly available with pacemaker. When the primary server goes down the secondary starts nfs service. Service IP is floating between servers but they have NO "shared" storage/filesystem so NFS state/connection information in case of failover is lost. I have two clients. When the failover from

Hi all. I am currently building a small test cloud based on Eucalyptus 2.0.3 and CentOS 5.8 x64. I have a choice which hypervisor to use: KVM or XEN. KVM is the default in CentOS 6 but I have read also many good things (for example PV guest machines, isolation between Dom0 and DomU) about XEN. Key factors from my opint of view are: - stability (which one runs more smoothly on CentOS?) -
