You mount your disk in the host or boot with live environment and run xfs_repair as it suggests. Make backup of the VM image before doing that. To have more detailed instructions, please, elaborate your question more: what virtualization system you use, how the VM disk is stored (file in some host file system? Logical volume? ZFS pool?), what means "VM had a power failure" — a host had a power failure perhaps, VM couldn't; also, what OS distribution is used in the VM — that suggests which tools are available directly in the initramfs.

Thank you very much, I'm using `VMware`, image is `centos7`, vm storage is host's disk, I mean, my physical machine had a power failure, VM was forced to shut down, as you said, I tried to use `xfs_repair`

So, what `xfs_repair -n /dev/sda1` said about you file system? Note that it should have xfs_repair utility included directly into the initramfs; you must have been able to run it from the initramfs emergency shell it dropped you into. Run xfs_repair with `-v` flag if you need more verbose output. `-n` doesn't write any changes, only detects and explains corruptions; this is safest way to run it for the first time to get an impression on the scale of the problem.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
