Comment # 3 on bug 1062383 from Liang Yan

Hi, Loic,

Are you trying to install a 42.3 vm on a 42.3 host? 
The error place is "WARN_ON(size != PAGE_SIZE && size != PMD_SIZE);"
so a wrong size page was picked for allocating new page.  

If possible, could you try same operation in a tumbleweed host environment?
thanks.
