Hello VB,

It looks like you haven't configured your Execution Point properly. Your job is not finding a match for the VM_TYPE. This line:

[5] 0 TARGET.VM_Type == MY.JobVMType

Your job is requesting a VM_TYPE of kvm. To check what the VM_TYPE your execution point is advertising use the condor_status command:

condor_status ep1ext.sel -ad vm_type

Please adjust your configuration as described in:

Once you set the VM_TYPE in the Exection Point's configuration, you can use condor_reconfig to reload the configuration and then check the result with condor_status. (You could also condor_restart (or systemctl restart condor) on the Execution Point.)

Thanks Tim, I did install condor_vm-gahp package (with apt, it is a Debian machine) and now the output is as follow:

# condor_q -better-analyze

The Requirements _expression_ for job 35.000 is

((Machine == "ep1ext.sel")) && (TARGET.Arch == "X86_64") && (TARGET.HasVM is true) && (TARGET.VM_Type == MY.JobVMType) && (TARGET.VM_AvailNum > 0) &&
(TARGET.Disk >= RequestDisk) && (TARGET.TotalMemory >= MY.JobVMMemory) && (TARGET.VM_Memory >= MY.JobVMMemory) && (TARGET.Cpus >= RequestCpus) && (TARGET.HasFileTransfer)

Job 35.000 defines the following attributes:

DiskUsage = 4250000
JobVMMemory = 4096
JobVMType = "kvm"
RequestCpus = 2
RequestDisk = DiskUsage

slot1@xxxxxxxxxx has the following attributes:

TARGET.Arch = "X86_64"
TARGET.Cpus = 12
TARGET.Disk = 11651356
TARGET.HasFileTransfer = true
TARGET.HasVM = true
TARGET.Machine = "ep1ext.sel"
TARGET.TotalMemory = 32130

The Requirements _expression_ for job 35.000 reduces to these conditions:

Slots
Step Matched Condition
----- -------- ---------
[0] 1 Machine == "ep1ext.sel"

Hello,

Please install the condor-vm-gahp package. Something like:

yum install condor-vm-gahp

apt install condor-vm-gahp

(I don't know which packaging system that your Linux machine is using.)

Hi Tim,

the execute node is a Linux machine, I did a find but I have not found the condor_vm-gahp executable.

Must I install a separate package ?
