Re: KVM snapshot process

[Geoff Higginbottom]

Ivan,

The Host actually copies the image to Sec Storage,  if this is very slow have 
you considered dedicating some NICs and configuring the CloudStack 'Storage' 
network and enabling Jumbo Frames etc.

Dear Cloudstack users,

Can someone explain me roughly the process of creating an snapshot in KVM ?

The process takes a very long time, the speed at what the qcow2 file is
copied from primary to secondary storage is extremely slow, on the storage
level
I can see is around 4 Mbps but I know our primary storage and secondary can
dump data faster than that

So far this is what I know

Step
   1.- Pause the VM in the host
   2.- Create the snapshot of the qcow2 files using qemu-img
   3.- Backup the image into secondary storage

So my question is who is actually copying that file over to secondary
storage ?
I've checked the secondary storage vm and it doesn't look like its playing
any role during this process.

Thanks in advance

Hi Geoff,

What if the VM is stopped and not running anywhere ?
which is my case.

We have 10 GB LACP and jumbo frames.

Re: KVM snapshot process

[Ivan Rodriguez]

What is the purpose of doing this

qemu-img convert -f qcow2 -O qcow2 -s

KVM is using qcow2 this is the bit that is slowing this whole process

This is required to take the disk snapshot, additionally your backing 
file might not always be QCOW2, it could be RAW (iSCSI/CLVM), CEPH etc, 
but the target file needs to be a (qcow) file so it can be stored easily 
on the NFS share.

Cannot add a host to Cloudstack

[Andrew Chiw]

Hello everybody, I’m playing with Cloudstack on a single server, which will 
host everything (primary/secondary storage). The problem is I can’t seem to add 
a host to Cloudstack (it takes a long time, and then after a while it says it 
failed). I want to add the same machine that Cloudstack is running on to 
Cloudstack so it will run Qemu+KVM on it.

What exactly does Cloudstack do anyway when I’m adding a host (physical 
machine)? Does it try to ssh in with root and do something? Why does it even 
need root/password? It says it was set when I installed the hypervisor - but I 
installed qemu-kvm, and I was never asked for a password. It doesn’t make sense 
anyway.

Thanks,
Andrew

Access console VM via custom portal

[dimas yoga pratama]

Hello,
can anyone answer my question?

I create a custom web portal that provide some provisioning for user
I want user can access cloudstack VM from my web , but I kept gtting this
message: "Access denied. Invalid web session or API key in request"

I already pass the sessionkey like this :
http://10.151.32.11:8080/client/console?cmd=access&vm=018f88b2-4edc-4e6d-b318-3ec02029180f&sessionkey=d01AlQ2ZzwKBVqB2Rkj0qsHP/aw=

how can I access it from outside cloudstack UI?  Is there any API that can
handle this request?

thanks, looking forward for the answr.

is there any tutorials for setting up CS using advanced network and KVM hypervisor?

Hi,

I have followed this run book to set up my first CS instance successfully with 
basic networking: http://people.apache.org/%7Eke4qqq/runbook/index.html .

Now I want to try advanced networking with kvm hypervisor where CS management 
server and kvm hypervisor are running on two separate physical nodes. Does any

Re: SSVM & CPVM Public IP not pinging

[ilya musayev]

In VMware world, which i assume is not much different from XEN, this 
usually means that the network system VM NIC inherited is incorrect


Here is what i wold do, while you are connected to a VM through console, 
initiate a ping to a gateway (continuous mode), change the sysvms 
network one by one, to see which one works.  Most likely, you have 
public and private in reverse. I assume they are untagged, if they are 
check what portgroups you have in XEN created.

RE: is there any tutorials for setting up CS using advanced network and KVM hypervisor?

[Sanjeev Neelarapu]

Apache cloudstack Install & Admin guides should help you in setting up this 
environment.

Hi,

I have followed this run book to set up my first CS instance successfully with 
basic networking: http://people.apache.org/%7Eke4qqq/runbook/index.html .

Now I want to try advanced networking with kvm hypervisor where CS management 
server and kvm hypervisor are running on two separate physical nodes. Does any 
one know a good and accurate tutorial or run book for such a setup ?

Thanks

Yiping

Like Sanjeev already mentioned, the Install+Admin guide should help you with 
the setup.
Alternatively, I have a step-by-step guide at 
http://shankerbalan.net/blog/cloudstack-simple-advanced-network-example/ which 
could use.

Hth.

Subject: Cannot add a host to Cloudstack

Hello everybody, I'm playing with Cloudstack on a single server, which will 
host everything (primary/secondary storage). The problem is I can't seem to add 
a host to Cloudstack (it takes a long time, and then after a while it says it 
failed). I want to add the same machine that Cloudstack is running on to 
Cloudstack so it will run Qemu+KVM on it.

What exactly does Cloudstack do anyway when I'm adding a host (physical 
machine)? Does it try to ssh in with root and do something? Why does it even 
need root/password? It says it was set when I installed the hypervisor - but I 
installed qemu-kvm, and I was never asked for a password. It doesn't make sense 
anyway.

Thanks,
Andrew

You are able to reach Google DNS because there is a static
route to 8.8.8.8 via the management subnet.

Can share the full output of ssvm-check.sh?

Can you ping the gateway? If not, it could be that:

1) 10.129.152.0 subnet is not routable or cant reach 10.129.152.1
2) eth2 is bridged to the interfaces labeled for public traffic

I would check if each of the virtual interfaces are bridged to the right
physical interface on the XenServer labeled interfaces.

tcpdump on all the interfaces on the SSVM and on the physical
interfaces will also help identify the issue.

Regards.

Apache Traffic Server is more focused on being a forward and reverse proxy
rather than a load balancer. The typical deployment architecture for ATS
or more specifically YTS (Yahoo Traffic Server) at Yahoo which I managed
was as below:

GSLB -> Hardware LB -> YTS Cluster -> Hardware LB -> App Cluster
