Hi ,

Have liberty setup on FC23 .I booted an instance with the following command :

 nova boot --flavor m1.small --image CentOS-6-gen   --nic net-id=c5500df3-d924-45c1-bd57-96a95258e973 --block-device id=54f12458-1aff-4bd2-8123-fd84768c9a2,source=volume,dest=volume,bus=ide,size=1,device=/dev/vdb,type=cdrom,bootindex=1 VM-cdrom

The VM is up and running , I see the volume as /dev/sr0 . But I cannot detach this volume neither via dashboard nor command line .

Hi ,

I have the Juno setup was done by Fuel 6.1 . HA but with one controller only and noticed that they changed the networking model - almost all networking settings were removed from the OVS .

The point is that a single VM does get IP . The problem starts when I run multiple VMs - only 50 % succeed to get IP .

I have a Juno HA deployed using Mirantis 6.1 and having the following problem - if I launch a single VM it gets IP from dhcp but when I run multiple VMs simultaneously only 50% of them succeed to get IP .

Any ideas ?

2015-03-11 10:11:34 -0500 commented question root file system size is wrong ?

I used a standart CentOS 6 image .

fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders .......

df -h

Filesystem Size Used Avail Use% Mounted on /dev/vda1 20G 1.2G 18G 7% /

As you see , the df gives only 20 gb

2015-03-11 06:20:48 -0500 asked a question root file system size is wrong ?

Hi ,

Why if I launched a VM with medium flavor ( 40 Gb disk ) its root file system is 20 Gb only ?

fdisk -l shows 40 Gb .

Hi ,

May someone advise how to configure a packstack answer file to manage a multimode setup ( RHEL based) with the following network types ( on controller ) :

  1. eth0 - for API
  2. eth1 - for RHEL/RHOS install.
  3. eth2 - for management network
  4. eth3 - private network
  5. eth4 - for storage ( iscsi ) .

Hi ,

It is possible to configure a network with its subnet with a specific DNS IP . How to make that each network in options will have its own domain name rather than it would be taken from global settings in the /etc/neutron/dhcp_agent.ini ?

Thanks .

2014-12-11 05:34:22 -0500 commented answer neutron-ns-metadata-proxy port is not available

The problem has been resolved - due to the link was sent I found that in a dhcp-optsfile for my dnsmasq process there was no option for the 169.254.169.254 . For some reason this route on VM didn't work: 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 Works now.

2014-12-11 02:28:54 -0500 commented answer neutron-ns-metadata-proxy port is not available

In my settings I have the same ones except these two lines in the /etc/neutron/dhcp_agent.ini

enable_isolated_metadata = True enable_metadata_network = True

  • without then a VMs do not see the 169.254.0.0 network

Hi,

In Juno RDO I cannot make my Vms will get a metadata from 169.254.169.254 .

I noticed that the neutron-ns-metadata-proxy is running with the following options - pls note the port - 9697 .

root     28243     1  0 13:42 ?        00:00:00 /usr/bin/python /bin/neutron-ns-metadata-proxy --pid_file=/var/lib/neutron/external/pids/4ee35a51-ab0d-4827-9bb1-5368f8f81ac3.pid --metadata_proxy_socket=/var/lib/neutron/metadata_proxy --router_id=4ee35a51-ab0d-4827-9bb1-5368f8f81ac3 --state_path=/var/lib/neutron --metadata_port=9697 --verbose --log-file=neutron-ns-metadata-proxy-4ee35a51-ab0d-4827-9bb1-5368f8f81ac3.log --log-dir=/var/log/neutron

In the other cluster I have ( Icehouse ) this service runs with --metadata_port=80

I inspected the ns status for dhcp net and neither port 9697 nor 80 do not show up there :

This explains why VMs cannot access the metadata .

Why neutron-ns-metadata-proxy runs without port up ?

Regards ,
