Table 1 Performance parameters used in virtual machine live migration method
From: A three phase optimization method for precopy based VM live migration
\(V_{mem}\) | Memory size of VM |
\(T_{mig}\) | Total migration time |
\(V_{mig}\) | Total pages transferred |
\(T_{down}\) | Downtime |
R | Memory transmission rate |
D | Memory dirty rate per iteration |
\(V_{i}\) | Volume of pages transferred at ith iteration |
\(T_{i}\) | Time taken for transferring pages at ith iteration |
\(V_{l}\) | Volume of Pages transferred in last iteration |
\(T_{l}\) | Time taken for transferring pages in last iteration |
\(V_{thd}\) | Threshold value required for last iteration |
\(T_{resume}\) | Time taken by VM to resume at target |
n | Maximum number of iterations |
Temp array used | TO_SEND_h to store historical statistics based on number of times page is updated |
