[Haizea] Multiple virtual machines on single physical machine

[Janki Akhani]

Hi,

I have done the same thing but i was getting error. So I have searched and found that one more correction is required which is in rpc_commands.py as shown below.
Changed line :
            capacity.set_quantity(constants.RES_CPU, int(self.opt.cpu * 100))

Originally it was :
            capacity.set_quantity(constants.RES_CPU, int(self.opt.cpu) * 100)

I got another problem. I am sending you requests.sh file which contains requests that i am submitting. I found that 8th lease in it should be scheduled but it is not happening. So can you please tell me that 8th lease should be scheduled or not?
I am also attaching sample_trace.conf file which I have used.

I have seen details of on which physical node each lease will be scheduled so i found that it should schedule 8th lease. To check this thing you will also have to do these two changes in rpc_commands.py file.First one which you told me and second one i have mentioned above.

Thanks & Regards,
Janki

Hi,

Haizea supports scheduling multiple VMs on a single physical machines
(with any number of CPUs). However, I just took a look at
haizea-request-lease, and it looks like there's a bug in how it
handles the "-c" parameter (it assumes it is an integer, so 0.5 is
probably being round up to 1). In src/haizea/cli/rpc_commands.py could
you try replacing this line:

 self.optparser.add_option(Option("-c", "--cpu", action="store",
type="int", dest="cpu",

With this:

 self.optparser.add_option(Option("-c", "--cpu", action="store",
type="float", dest="cpu",

If that doesn't work, please send me all the commands you are running,
Haizea's config file, and Haizea's output when you run them.

Cheers!
