Description

How to test

  1. edit the guest <memory> section 
     # virsh edit <guest-name>

     <memory>1048576</memory>

     <currentMemory>524288</currentMemory>

     # virsh start <guest-name>

      

    

  2.  set guest memory using non-integer 
    # virsh setmem <guest-name,id,uuid> abc
    

  3.  set guest memory larger than max memory 
    # virsh setmem <guest-name,id,uuid>1248576
    

  4.  reduce guest memory 
    # virsh setmem <guest-name,id,uuid> 655360
    

  5.  reboot guest then check the memory

     
     # virsh shutdown <guest-name>

     # virsh start <guest-name>

     # virsh dumpxml <guest-name>

     login guest

     guest> cat /proc/meminfo | grep -i memtotal

     

    



  Expected Results 


  1.  Step#1: guest started successfully

  2.  Step#2: error: Invalid value of 0 for memory size

  3.  Step#3: error: Requested memory size 1248576 kb is larger than maximum of 1048576 kb

  4.  Step#4: return nothing

  5.  Step#5: the memory of guest is approximate to 655360
