So the default now is ext4 for all linux with\nthis commit. Also note that for non-linux and non-windows\nthe default used to be ext3, now it is vfat.\n\nNote that there is still support for ext3 as the default if some\ndeployers do choose to keep that as the default, by using either\nvirt_mkfs or default_ephemeral_format configuration option. We\nare just trying to move the default for everyone who is starting\nfresh.\n\nOriginally logged by lifeless as I833356af81df743a63d4442d389be82bc25f3914,\nreverted in I8de225729bbc77b263fcac2fa72b0e9cc6c1b2bf by phil and re-proposed\nby swapnil in Ibe9e9ba4265125c5bd933cde1a93cca02511bb46\n\nDocImpact\n\nCloses-Bug: #1266262\nChange-Id: I92cb51c6118e48fd66ada0e2fee624597c4ad8f0","distinct":true,"url":"https://api.github.com/repos/mandeepdhami/nova/commits/7517108e7ad40befc1f18a9978aa1080916f7246"},{"sha":"e71e89c840ee68b3ae60099ff1ad59e5548c97fd","author":{"email":"d95b56ce41a2e1ac4cecdd398defd7414407cc08@review.openstack.org","name":"Jenkins"},"message":"Merge \"Support for ext4 as default filesystem for ephemeral disks\"","distinct":true,"url":"https://api.github.com/repos/mandeepdhami/nova/commits/e71e89c840ee68b3ae60099ff1ad59e5548c97fd"}]}
