Delete "--no-hug -m 1024" parameter in testcase.And if we want to add "--no-hug
-m 1024" parameter in vhost-user(back-end side), we can use "echo 1000000 >
/sys/module/vfio_iommu_type1/parameters/dma_entry_limit" command or adding "
vfio_iommu_type1.dma_entry_limit=1000000" in bootargs.
So close this bugzilla.
