      I'm just saying what is a working variable on my server 🙂

      XenServer 7 or CentOS?

          CentOS, because XS7 doesn't work.

            Is that after updating the yum.conf variable?

              That is after setting it back to the default of distroverpkg=centos-release.

                Okay, that's what I thought.

                And yum still isn't working? Might have to just put in the manual repo updates then.

                  It looks like /etc/centos-release isn't where that value is being pulled from. I edited the file and it didn't change the output of yum version.

                    Well, I just went in and replaced every $releasever with 7 in the .repo files. I can now access yum. Now to figure out how to get my hands on drbd...

                      Using XO VM replication between 2 XS 7 hosts, initial copy of a 61GB VM in 8 minutes:

                      0_1464216106445_fast_replication.png

                      This is on a classic GB link.

                      Clearly, previous bottlenecks weren't in XO.

                      I have not seen anything like this on importing and exporting yet.

                      I am still getting super slow speeds.

                      Once I get all the VMs set up on the same machine, I will do some official testing.

                        So you'll have to find the super slow bottleneck 😛

                        My lab is pretty simple, if you need more info on how I achieved those speeds, tell me 🙂

                          Well, in theory if I have two machines on a 1GB link, I should see speeds similar to yours, right?

                            There is no magic: you need to have enough write speed on the target and read speed on the source.

                              Yeah, I'll set up some tests once I am done getting everything set back up.

                              Right now it's clipping along at 5MB/s so it's taking forever.....

                                What is the sustained write speed on a SATA drive? I'm guessing it must be a lot lower than 120 MB/s??

                                  Depends of the drive, roughly between 40 and 60 MiB/s

                                  edit: for a HDD

                                    Something is wrong with that picture. Even older SATA drives can hit 100MB/s. 100MB network connection could be topping out at that.

                                      For me, this is SSD going to SSD.

                                      Granted, this current import is from my 100mbps desktop connection, but still, 40mbps is slow.

                                        I'm importing a 40GB VM, and it's already been almost 2 hours, which is about what 40GB takes to transfer at 5MB/s.

                                          That's within reason for a 100Mb network connection. The best I've seen out of a 100Mb network is 9MB/sec, that's on a network with zero other traffic.

                                            @BRRABill 1Gb networks are much nicer, and not any more expensive anymore. For future consideration.
