Migrating VM fails with DUPLICATE_VM error part2
-
Yeah after taking a look, found this: https://github.com/xapi-project/xen-api/blob/d496b90c4172f71337841dcacb3496751141f712/ocaml/xapi/import.ml#L246
It might be duplicated MAC address related.
-
@olivierlambert
Funny you say that, look at where we both commented on last year
https://xcp-ng.org/forum/topic/3182/centos-ovas-imported-from-esx-network-hang/34?_=1636230593687Checked the MAC addresses of the two vms (the imported ones) but they are different. I'll try a side by side comparison of all the objects.
-
@andres
Both vms exported from esxiWindows 10 vm

-
Can you check if you don't have any similar MAC on the destination host?
About the seed, well, in theory that shouldn't be a problem, but you can always replace it by another random UUID (here is one I got with
uuidgen:3ec7fc14-1e25-4453-b3f9-5a7b6554d241). -
@olivierlambert
Similar, but not the same; the two imported vms have MAC addresses that differ only by one ( 9e:86:37:32:02:d7 vs 9e:86:37:32:02:d8) which should be enough.
Visually checked all MAC addresses on the destination host via XO, nothing even close except the D7 vs D8.
Is there a way to dump all object from all vms on a host? -
Yes but I don't remember. Let me try if I can find this quickly.
-
You can do a
xe vm-vif-list params=vm-name-label,MACto see all your VMs MACs at once. -
@olivierlambert Thanks, this confirms that there is no MAC address clash.
The fact that they are both imported the same way from the same source system is a strong suggestion that something is clashing, especially after the MAC address issue found last year.Suggestions are welcome, otherwise I might entertain myself and recreate a Windows 10 vm on the destination and symply copy over and connect the disks.
Let me know if you want me to provide details or create a ticket somewhere.
-
Well, I'd love that we could find the culprit
xe vm-list params=allwill give you all the params for all VMs on a given host.Then, you should try to compare between 2 hosts and see if there's similar fields that shouldn't be similar (I know, it's vague).
In the mean time, let me ask around to some XAPI devs.
-
@olivierlambert Appreciated. I will go through the fields to see if anything looks odd..
-
@olivierlambert Nothing odd that stands out for me when comparing the data.
Additionally I tried migrating the (most likely) offending vm from the other host and I get the same error.
Migrated two other (created on xcp-ng) vms but those fail with a VDI_COPY_FAILED but the migration starts properly. Only at the end I get this error.vm.migrate { "vm": "0ab24395-becb-71f4-4f93-066c2d660cff", "mapVifsNetworks": { "651db47e-129a-7152-f988-cc4408abce0a": "a014b230-2db6-adb4-ba4f-0b1cc07fdcae" }, "migrationNetwork": "a014b230-2db6-adb4-ba4f-0b1cc07fdcae", "sr": "270f8f4a-a24c-ced6-99c7-9bc2ba5f5008", "targetHost": "3b57d90b-983f-46bb-8f52-4319025d1182" } { "code": 21, "data": { "objectId": "0ab24395-becb-71f4-4f93-066c2d660cff", "code": "VDI_COPY_FAILED" }, "message": "operation failed", "name": "XoError", "stack": "XoError: operation failed at operationFailed (/opt/xo/xo-builds/xen-orchestra-202111061645/packages/xo-common/src/api-errors.js:21:32) at file:///opt/xo/xo-builds/xen-orchestra-202111061645/packages/xo-server/src/api/vm.mjs:482:15 at Object.migrate (file:///opt/xo/xo-builds/xen-orchestra-202111061645/packages/xo-server/src/api/vm.mjs:469:3) at Api.callApiMethod (file:///opt/xo/xo-builds/xen-orchestra-202111061645/packages/xo-server/src/xo-mixins/api.mjs:304:20)" }Now I need to figure out what the real issue is.
-
Can you also try with
xetoo? Maybe the error message will be more clear. -
@olivierlambert Life happened, just spent some time working through scenarios.
Using
xe vm-migrateI can move vms from one host to the other (this is across pools) and back. For me this rules out a host level issue.When I try to move the vms that won't migrate in both cases I get the error
Cannot restore this VM because it would create a duplicateThis clearly points at the two vms that were imported from esxi last year.
Reviewed the output of
xe vm-list params=all uuid=<relevant vm uuid>again and finaly noticed that they both have the samemac_seed:value underother-config (MRW):other-config (MRW): auto_poweron: true; vgpu_pci: ; base_template_name: Other install media; mac_seed: 5e88eb6a-d680-c47f-a94a-028886971ba4; install-methods: cdromand

-
Please modify the mac seed and see if it still trigger the error
-
@olivierlambert Thanks. Done that.
Next stop isxe vm-migrate remote-master=172.25.10.11 remote-username=root remote-password=xxxxxx vif:f4b175c2-0082-212c-b9d9-bd616cd83d2c=a014b230-2db6-adb4-ba4f-0b1cc07fdcae vm=Win10vm Performing a Storage XenMotion migration. Your VM's VDIs will be migrated with the VM. Will migrate to remote host: xen1, using remote network: Pool-wide network associated with eth0. Here is the VDI mapping: VDI 4d4a809d-6801-4462-8e52-811882106821 -> SR 270f8f4a-a24c-ced6-99c7-9bc2ba5f5008 VDI 6a30ca10-a386-4e00-91aa-89c3e5bd43de -> SR 270f8f4a-a24c-ced6-99c7-9bc2ba5f5008 There were no servers available to complete the specified operation.Doesn't matter what I set the
mac_seedto: empty, just a few characters or change one character. Setting it back to the 'original' value reproduces the earlier error about creating a duplicate so themac_seedvalue is making a difference. But there seems to be more.I couldn't find anything specific on
There were no servers available to complete the specified operation.on the forum, just one hit; someone asking what it means.A wider internet search showed some Citrix /Xen related posts; one about a DVD image not being available anymore so I disabled the DVD but that also made no difference. There is more than enough storage available on the receiving SR; more than double what is needed.
But now it gets interesting. When I try to start the vm again I get this:

mac_seedvalue does not even allow me to start the vm. I do get the ' duplicate' error on vm migration.When I start via xe I get
xe vm-start vm=Win10vm There are no suitable hosts to start this VM on. The following table provides per-host reasons for why the VM could not be started: xen2 : Cannot start here [Not enough free memory] There were no servers available to complete the specified operation.There is enough free memory (9 Gb available, 6 Gb requested). Even freeing up 15 Gb of memory does not make a diffence. Same errors in XOA and via xe.
Any other suggestions?
-
- So it seems that MAC SEED was the initial issue?
- Can you display the
xe vm-param-list uuid=<VM UUID>?
