Cannot export OVAs
-
I saw in the 5.77 XO Blogpost about how OVA exports are now twice as fast, however I can't get VM's to export OVA at all, either before 5.77 or on 5.77. It's always ends up failing after a minute or 2 with browser reporting "network error".
I've tried with the VM running and shutdown, maybe I'm missing the right way to do this? Thanks.
-
@florent That works much better for me! I was able to quickly OVA export VMs that failed before. Memory usage on XO was normal and did not grow. Download speed was good most of the time at 30-35MBytes/sec. It would pause occasionally but toward the end it picked up to 50-60MBytes/sec.
-
@sluflyer06 Hmmm... I thought just XVA was supported and you'd have to download and run XenConvert to go from XVA to OVA. I'm not sure, but maybe OVA exports have been deprecated for a while?
-
@tjkreidl I mean this was posted just a week ago about how OVA generation is much faster now, so I assume its not deprecated?
-
OVA exports were deprecated in XAPI/XenServer/XCP-ng, but here it's generated by Xen Orchestra
@sluflyer06 it's hard to assist more without details. Are you using XOA or XO from the sources? Any error in Settings/logs? Anything in the browser console?
-
@olivierlambert XO from sources. No error log in XO. Here is what the Chrome console spits out when it fails
-
It's hard to really know what's going on if you are using it from the sources (Node version, environment, current commit etc.)
Could you please try with a real XOA on the
latestchannel and try again? -
@sluflyer06 Sorry, I was not aware of that posting. My bad! Nice to see it show up as a feature.
-
@olivierlambert I just did a XOA deploy from the website and switched to latest and updated. Still failed. no error in XOA.
-
So that's a bug then
Can you give more info on the VM you are trying to export? (how many disks, networks and such)
-
@olivierlambert it happens on more than more, i think i've only had 1 successfully export, all my VMs have just 1 disk and 1 network, some are windows and some are linux. I'm happy to provide/submit anything that helps you guys out.
-
If you can find any common thing about the failing VM, that might be useful. The challenge for us is to be able to reproduce the issue so we can find what's causing the problem
-
@olivierlambert the only thing i'm really noticing outwardly is that the only VM's that will export have much smaller drive sizes than the rest. The 3 that will export have 20GB or less drive size, the others are as you see, larger, but not really big. XO-proxy is built on the same ubuntu server build as my plex VM so its not just a windows vs linux thing.
-
That's already a clue
-
@olivierlambert Do you need at least as much free space on the SR (in particular, if the VM running) as there is storage space for this to work?
-
@tjkreidl FWIW my SR is low utilization
-
We need to try internally on "larger" VMs if we can reproduce the issue
-
@sluflyer06 Ah,
definitelyprobably not the issue! -
Tomorrow @Darkbeldin could you try to export a VM with a disk bigger than 25GiB in OVA? (on XOA latest). Thanks!
-
@olivierlambert Trying it now I keep you updated
-
I tried an export on Edge (vs chrome), it got to 475MB before it failed, which is further than it gets in chrome...doesn't seem very helpful though.
