HI,
I have test.c VMware VIX script in execution node which look for running
vm and if there is no running vm then it start a fedora vm.
the test.c:
#include <stdio.h>
#include <stdlib.h>
#include "vix.h"
#define CONNTYPE VIX_SERVICEPROVIDER_VMWARE_PLAYER
#define HOSTNAME NULL
#define HOSTPORT 0
#define USERNAME NULL
#define PASSWORD NULL
#define VM_NUMBER 4
int vmHandleIndex = 0;
int runningVMCount = 0;
VixHandle hostHandle = VIX_INVALID_HANDLE;
char *runningVM[VM_NUMBER];
static void find_runningVM(VixHandle jobHandle,VixEventType ev,VixHandle
moreEvInfo,void *cd)
{
VixError err = VIX_OK;
char *loc = NULL;
if (VIX_EVENTTYPE_FIND_ITEM != ev) {
return;
}
if (runningVMCount < VM_NUMBER) {
err =
Vix_GetProperties(moreEvInfo,VIX_PROPERTY_FOUND_ITEM_LOCATION,&loc,VIX_PROPERTY_NONE);
if (VIX_SUCCEEDED(err)) {
runningVM[runningVMCount] = loc;
runningVMCount++;
} else {
fprintf(stderr,"GetProperties failed (%s)\n",Vix_GetErrorText(err,
NULL));
}
} else {
fprintf(stderr, "Warning: found too many virtual machines!\n");
}
}
int main(int argc, char **argv)
{
VixError err;
VixHandle jobHandle = VIX_INVALID_HANDLE;
VixHandle vmHandle = VIX_INVALID_HANDLE;
int i;
jobHandle =
VixHost_Connect(VIX_API_VERSION,CONNTYPE,HOSTNAME,HOSTPORT,USERNAME,PASSWORD,0,VIX_INVALID_HANDLE,NULL,NULL);
err =
VixJob_Wait(jobHandle,VIX_PROPERTY_JOB_RESULT_HANDLE,&hostHandle,VIX_PROPERTY_NONE);
Vix_ReleaseHandle(jobHandle);
if (VIX_FAILED(err)) {
fprintf(stderr,"Failed to connect to host
(%s)\n",Vix_GetErrorText(err, NULL));
goto abort;
}
printf("About to find running virtual machines\n");
jobHandle =
VixHost_FindItems(hostHandle,VIX_FIND_RUNNING_VMS,VIX_INVALID_HANDLE, -1,find_runningVM,NULL);
err = VixJob_Wait(jobHandle, VIX_PROPERTY_NONE);
Vix_ReleaseHandle(jobHandle);
if (VIX_FAILED(err)) {
fprintf(stderr,"FindItems failed (%s)\n",Vix_GetErrorText(err,
NULL));
goto abort;
}
printf("Listing running virtual machines\n");
printf("number of running virtual machine: %d\n", runningVMCount);
for(i = 0; i < runningVMCount; ++i) {
printf("%s\n",runningVM[i]);
}
if(runningVMCount > 0)
{
printf("can not start more virtual machine\n");
goto abort;
} else {
printf ("about to open \n");
jobHandle = VixVM_Open(hostHandle,
"/home/condor/vmware/Fedora/Fedora.vmx",NULL,NULL);
err = VixJob_Wait(jobHandle, VIX_PROPERTY_JOB_RESULT_HANDLE,
&vmHandle, VIX_PROPERTY_NONE);
Vix_ReleaseHandle(jobHandle);
if (VIX_FAILED(err))
{
fprintf(stderr, "failed to open virtual machine (%"FMT64"d
%s)\n", err,
Vix_GetErrorText(err, NULL));
goto abort;
}
printf ("opened (%d)\n", vmHandle);
printf("powering on\n");
jobHandle =
VixVM_PowerOn(vmHandle,VIX_VMPOWEROP_LAUNCH_GUI,VIX_INVALID_HANDLE,NULL,NULL);
err = VixJob_Wait(jobHandle, VIX_PROPERTY_NONE);
Vix_ReleaseHandle(jobHandle);
if (VIX_FAILED(err)) {
fprintf(stderr, "failed to power on virtual machine
(%"FMT64"d %s)\n", err,
Vix_GetErrorText(err, NULL));
goto abort;
}
printf("powered on\n");
}
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
abort:
VixHost_Disconnect(hostHandle);
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
}
to compile I use a make file:
WRAPPER = -lvixAllProducts -ldl
SERVER11 = /usr/lib/vmware-vix/lib/server-1/32bit/libvix.so
WORKST60 = /usr/lib/vmware-vix/lib/ws-3/32bit/libvix.so
SERVER20 = /usr/lib/vmware-vix/lib/VIServer-2.0.0/32bit/libvix.so
WORKST65 = /usr/lib/vmware-vix/lib/Workstation-6.5.0/32bit/libvix.so
WRAPORNOT = $(WRAPPER)
VIXH = -I/usr/include/vmware-vix
all:test
test: test.c
gcc $(VIXH) test.c -o test $(WRAPORNOT)
clean:
rm -f test
when run on terminal it gives the following output and starts the vm:
[condor@aopcach experiment]$ ./test
About to find running virtual machines
Listing running virtual machines
number of running virtual machine: 0
about to open
opened (34603069)
powering on
powered on
[condor@aopcach experiment]$
when executed with condor using the following submit file:
Universe = vanilla
transfer_executable = false
Executable = /home/condor/experiment/test
Log = simple2.log
Output = simple2.out
Error = simple2.error
Requirements = (Machine == "aopcach.uab.es")
run_as_owner = true
copy_to_spool = false
Queue
it gives the following output without starting the vm. here submit node
and execute node is same:
[condor@aopcach ~]$ cat simple2.out
About to find running virtual machines
Listing running virtual machines
number of running virtual machine: 0
about to open
opened (35651645)
powering on
[condor@aopcach ~]$
if I use the following submit file then the job keeps running for
indefinite time:
Universe = vanilla
transfer_executable = false
Executable = /home/condor/experiment/test
Log = simple2.log
Output = simple2.out
Error = simple2.error
Requirements = (Machine == "aopcach.uab.es")
run_as_owner = true
copy_to_spool = false
should_transfer_files = YES
when_to_transfer_output = ON_EXIT
Queue
with simple C program, everything runs fine. But with VIX, I am facing the
problems.
