Re: Fail to configure network interface when booting VM

[Du Jun]

Hi Neelarapu,

I am sorry that I did not describe my situation clearly. I am using ubuntu,
and output of `ifconfig -a` shows
the name of interface is "eth0", it has mac address.

When I have a look at /etc/network/interfaces, it shows:
auto eth0
iface eth0 inet dhcp

What's more, I use the same template in the host A, and the interfaces of
VM is okay.

BTW, from web UI, I can see the nic of the VM, but the ip address is
missing when I type `ifconfig -a`. It's so
strange!

RE: Fail to configure network interface when booting VM

[Sanjeev Neelarapu]

Hi Jun,

There could be some issue with the template with which you deployed vm. Please 
check "ifconfig -a" output in vm booted on hostB.
This will give the interface name and make sure that network-scripts directory 
has a file with the interface name.

You can stick it somewhere in the rc scripts. rc.local would be a good place.

Caveats - changes will be lost if CPVM is recreated or when a system VM 
template is updated.

About VM network interfaces

[Du Jun]

Hi all,

I have two servers, host A as management server and host B as agent host.
The vms booted from host A can access the internet freely and I can access
host A from outside. But, the vms booted from host B have trouble in
configuring its network interface.

For example, from web UI, the VM booted from host B has nic 10.1.1.121.
Indeed, I can also see the information about the dhcp in
/var/dhcp/dhclient.eth0.lease. Everything seems okay. However, when I type
`ifconfig` in the VM, I can't find the ip address 10.1.1.121.

PS: I am using CS 4.2 advanced zone, KVM hypervisor. Both host A and host B
have configured network bridge "cloudbr0".

I really have no idea now, please give me some clues. Thanks!

Du Jun

Hi Umair (sorry missed the 'i' last time)

Haven't been able to digest your logs but one common problem with 
XS is

forgetting to get the specific vhd-util mentioned in the docs:
section 4.5.3.3 of
https://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.2.0/html/Installation_Guide/management-server-install-flow.html 

If you missed this, you can manually copy that vhd-util to the XS 
hosts

to /opt/xensource/bin/

Also if you are using basic network, don't forget to switch the XS 
hosts to

bridge (xe-switch-network-backend bridge)

Finally one thing that has helped me is to disable iptables on the 
XS hosts

(service iptables stop; chkconfig iptables off)

Carlos

Re: about openvswitch

[Carlos Reátegui]

Steven,
I am using ovs on xenserver 6.0.2 and 6.1 with CS 4.1.  The main benefit for me 
was being able to create 4 nic bonds, with bridge you are limited to 2 nics per 
bond.  The downside however is that you can not use security groups in a basic 
network so I had to create an offering without them.  For my use that was ok.  
This may have changed in more recent versions of CS.

Hi Carlos,

I see following management servers logs, what could be the possible 
reasons for these exceptions.

If you had it on the management server then it would have been copied over to 
the hosts when you added them and there is no need for you to do it now.

Hi,

Carlos thanks for the follow up I really appreciate that, Well i have got the 
vhd-util placed in 
/usr/share/cloudstack-common/scripts/vm/hypervisor/xenserver/vhd-util on 
managment server but missed to place it on XS host in /opt/xensource/bin. I 
probably missed or couldn't find anything in cloudstack installation guide to 
place vhd-util in Xen hosts at /opt/xensource/bin.

I will do that right away and see if it works or not. Thanks again

Hi Umair (sorry missed the 'i' last time)

Haven't been able to digest your logs but one common problem with XS is
forgetting to get the specific vhd-util mentioned in the docs:
section 4.5.3.3 of
https://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.2.0/html/Installation_Guide/management-server-install-flow.html
If you missed this, you can manually copy that vhd-util to the XS hosts
to /opt/xensource/bin/

Also if you are using basic network, don't forget to switch the XS hosts to
bridge (xe-switch-network-backend bridge)

Finally one thing that has helped me is to disable iptables on the XS hosts
(service iptables stop; chkconfig iptables off)

regards,
Carlos

Hi carlos,

I have changed switch ports, cables etc, I am successfully able to mount

Hi Umar,
Did you verify your network per Shanker's suggestion?  You need to make
sure the NIC flapping is fixed first before you can expect anything to run
stably.  When you say you are able to mount it manually, did you also try
copying data over that mount?  I had a similar problem once and it ended up
being a bad cable.

Hi,

copied.

about openvswitch

[Steven Liang]

Hi,

I found from the document that we can use openvswitch instead of
traditional bridge.
Who can tell me the benefit using openvswitch?
I used basic zone, and I cannot read usage info. If I use openvswitch,
can I get usage info?
Thank you.

Regards,
Steven

Re: SSVM Not coming up

[TommyBW]

Hi Suresh, 


That is what I thought so I copied it from the cloudstack manager. 

Perhaps I copied to wrong location. Can you give me the right path on xenserver 
6.2 host ? 

Kind regards,

RE: How to modify system vm's iptables rules

[Joaquin Angel Alonso Alvarez]

Hi,

Due to a particular network configuration on the platform we need to access the 
console proxy from the private IP address and it comes blocked by default for 
that interface, it´s open only for the public interface.
At the moment I ssh into the Console Proxy VM and add the rule myself (or just 
disable the iptables at all), but it´s not permanent.

Kind Regards,

Primary Storage PreSetup Configuration

[iliyas shirol]

Greetings !

Do we want to use the *presetup* configuration of the primary storage if we
want to define timeout(s) for iSCSI mounts / NFS shares from a central
storage ?

We are using XenServer-6.2 as our hypervisor.

Thanks.

VHD file of a template is deleted from Secondary Storage

[Marco Sinhoreli]

Hi community:

I have some templates registered in ACS like Windows, CentOS, etc. When I asked 
to download these templates, after some time (I don't know the exact time) the 
VHD file go away from the secondary storage. Have no information in the ACS 
logs about it or anything. The template.properties metafile remain there but 
the VHD file no. In the database and UI the template is apparently ok and ready 
to use. If I try to build an instance from any template that have no VHD file 
it fail. The link below is a similar issue I have:

Re: Fail to configure network interface when booting VM

[Du Jun]

BTW, the /etc/cloudstack/agent/agent.properties is shown below:
#Storage
#Mon Mar 10 16:59:56 CST 2014
guest.network.device=cloudbr0
workers=5
private.network.device=cloudbr0
port=8250
resource=com.cloud.hypervisor.kvm.resource.LibvirtComputingResource
pod=1

domr.scripts.dir=scripts/network/domr/kvm
LibvirtComputingResource.id=10
host=10.10.101.103

We can see that, guest, private and public all use the network bridge
"cloudbr0". And, route table in my agent host(B) is like that:

cloud0
192.168.122.0   0.0.0.0 255.255.255.0   U 0  00

It seems all okay. I wonder what I have missed?

Re: Fail to configure network interface when booting VM

Hi Bharat,

Thank you for your prompt reply. As I am new to CloudStack, I have 2
questions to consult you.

>check if host B  has the systemvm.iso in it. if not copy it manually from
host A.
Where can I check if host B has the systemvm.iso?

>before adding the host make sure the host tags are cleared.
When I add the host B, the tag of the host is empty. After adding the host,
I add a tag for host B so that I can always put the VM to host B for
testing purpose. Does it matter?

Re: Fail to configure network interface when booting VM

[Bharat Kumar]

Hi Jun,

check if host B  has the systemvm.iso in it. if not copy it manually from host 
A. 

cloudstack generally dose this for you when you add a host for the first time.
before adding the host make sure the host tags are cleared.

Bharat.

Fail to configure network interface when booting VM

[Du Jun]

Hi all,

I am using CloudStack4.2 advanced zone in Ubuntu12.04. I use host
A(10.10.101.103) as my management server, and use host B(10.10.101.107) as
my agent host. I meet a problem that the VM booted in host B fail to
configure network interface when boot up. In other words, when I type
`ifconfig` in VM booted in host B, I find the IP address is missing!
However, there is no problem with the VM booted in host A.

BTW, I both add a network bridge "cloudbr0" in management server(A) and
agent host(B). Both server A and B can access the internet and I can access
them from outside. So, I have no idea now. Can anyone tell me how to debug
or provide me with some clue? Thanks!
