Hello, I have 4x 1TB in raid 10 and adaptec 5405 root@web [~]# time 'dd if=/dev/zero of=/home/10G bs=1M count=10240; sync' -bash: dd if=/dev/zero of=/home/10G bs=1M count=10240; sync: No such file or directory real 0m0.001s user 0m0.000s sys 0m0.001s Whats the error?

Hello, I'm trying the disk type options, and really dont see any differences. For KVM guests running centos 5.5 x64 what would be the best ( ide, virtio, scsi )? In image format what do you suggest ( raw, vmdk, qcow2 )? thanks

Still testing the solution. Is there any way to migrate from local storage to shared storage ( iscsi in the case )? How can i copy the vm?

Ok, i was able to do it, thanks! I have now eth0 - vmbr0 with my external IP and eth1 with a 10.11.0.X IP in each server. Cluster use the external IP to connect, but i would like to create the cluster using the 10.11.0.X IP in order to get faster live migrations ( as its a 1Ge only for this...

Hello, O will check that and update the ticket quickly. Regarding the network part / NAT, that's very important, can you please provide more detailed information?

Hello, Yes, nics are fully supported. I'm seeing memory usage in proxmox ( vm details ), and in a top. Since i'm only in tests, its a normal server c2d, with a 500gb drive. However if i copy a file from the nfs box to the proxmox host its much more faster. Regarding the nic configuration...

Hello, I'm testing proxmox and a few other alternatives ( xenserver, vmware ), in order to virtualize a few dedicated servers. I setup a 2 machines cluster and a nfs storage ( in production will use a SAN and iscsi ). I have however a few problems: 3 Of created vms ( all kvm ), have almost...

hello, i configured a san with open-e, and then created a volume group. However, proxmox only detect the lun if the volume is created as a block-io, and not as file-io. However open-e, recommends this to be created as file-io. Also, when i create as block-io, it will use the whole space of the...

thanks a lot for your help and fast answers. probably both, but a bigger number of kvm.

So, if they are local i cannot live migrate kvm, only openvz, correct?

I'm testing, and noticed that i cannot make live migrations of kvm vm's. I'm using raw format ( its the fastest, correct )? Any way to move the vms live?

I will have vms with about 300gb, and may need to do live migrations. Atm in my servers, i have eth0 for internet access, and eth1 to a backend network ( other switch etc ). If i make live migrations using the same nic as vms are connected to internet it will take years, no? Maybe i'm in a big...

this is all new for me. Since server have two nic's, how can i force it to use one for cluster communication ( using another vlan ) and one to access vms/proxmox? Probably is easy, but i'm not getting it :S

Ok, i have setup a few kvm vm's. openvz will not be an option since i need to add r1soft cdp installed, and openvz doesnt support it. I will need to install it per vm and kvm is the only option. What worries me is the IO problem, as i cannot add sites and have slowness compared to dedicated...

Hello, Maybe i didnt explain well. I will access proxmox/vms eith vmbr0/eth0, but i want cluster communication to use eth1. Atm i have a switch where eth1 port on servers connect to make backups, so would be much faster than using eth0 ( that have internet traffic ). The idea is to separate it...

Hello, So we cannot create a cluster using eth1 for example? I want to have vmbr0 to internet access, but cluster/management to be made using eth1. Isnt this possible?

Hello, So, openvz should be the best option, even if it isnt a total virtualization platform. Regarding hardware, i'm thinking about this: 2x INTEL XEON SIXCORE L5640 24GB RAM DDR3 8x 300GB SAS 15k RPM Seagate Cheetah or 4x 600GB. What is best? Atm i use adaptecs 5405 and 5805, but i should...

thanks for your help. The IO problem also apply to openvz?
