Hi There! 

 

I  have an issue in getting cpu utilisation/memory utilisation for all
slave nodes. The xml-rpc function returns "0.0" for cpu utilisation .
Reading the rrd files, does not provide the details for other
hosts(Slave ones). 

Can you provide some guidance how can I get statistical  data for all
the xcp hosts?

 

Regards

Akshay

Hi there,

 

We are using latest version of XCP on 6 hosts. While issuing VM.start or
VM.start_on xmlrpc functional call , it says :

 

 

{'Status': 'Failure', 'ErrorDescription': ['SESSION_INVALID',
'OpaqueRef:cfb6df14-387d-40a1-cc27-d5962cba7712']}

 

However if I put VM.start in a loop maybe after  20-30 tries it succeeds
. 

But VM.start_on does not succeed even after 70 tries.

One more observation -  VM.clone succeeds after 7-8 tries 

VM.hard_shutdown works fine 

 

Can you guide me on this issue,

Akshay

IIRC, there was a fairly nasty session caching bug that could cause issues like this. It's been fixed since, and the upcoming 0.5 release (coming in a week or so) should fix it.

Cheers,

Jon

There aren't any binaries at the moment, but you could build your own from the public repositories - I sent a script out on the 25th March that will compile everything up. You'll need to replace the xapi and fe executables (xapi is output in xen-api.hg/ocaml/xapi/ and fe is found in xen-api-libs.hg/forking_executioner/)

I'll reattach the script to this mail.

Hello, I was wondering if there is a i386 version of the "Base" Iso, since
the base one was 64 bit it did not run on my HP DL380 G3. if you can point
me in the right direction on how I can put your set up on my server you
would make me the happiest man alive thats been trying to set up a cloud for
months now.

I'm pretty sure that XCP targets only 64-bit x86 processors.

Yes, XCP requires 64bit CPU.

Dom0 Linux in XCP is 32bit, but the Xen hypervisor is 64bit.
