Re: [Xen-API] Storage Repository FileSR on ZFS won't work - Linux

[Dawid Kowalski <dkadds2@xxxxxxxxx>]

Germano,

Many helps for your tips.

Looks like I'm running even if latest master branch, some kind of old version as all I have is:
grep CONF_KEY_ /usr/lib/xapi/sm/blktap2.py
ÂÂÂ CONF_KEY_ALLOW_CACHING = "vdi_allow_caching"
ÂÂÂ CONF_KEY_MODE_ON_BOOT = "vdi_on_boot"
ÂÂÂ CONF_KEY_CACHE_SR = "local_cache_sr"

If you're anyhow familiar which Xenproject even non GA version it the right one to go, that would be great.
All I need is to put it on top of base Ubuntu 14.04 as can't go with packaged XenServer.iso due to some requirements on my side (full hdd necryption).

Certainly I don't question power behind Xen, as this is one of the reasons why I turned into this direction. Personally I do know large companies using Xen/CitrixXen implementation for long time already.

It's only that in my case I've run into so many issues, that it brought me to thoughts as expressed earlier. Regardless of issues I've run into, using different workarounds I'm heading to my target.

What I really like about Xen is the PVM.

All help from you and others is more than appreciated. Thank you!

Hi Dawid,

For what concerns your build I do not know how it maps to storage
manager and blktap versions.
If in /opt/xensource/sm/blktap2.py there is a line like

CONF_KEY_O_DIRECT = "o_direct"

then you can disable o_direct.

About your frustration I can understand but it is a long shot
to say xenserver is in beta stage, given there are many huge
business running on top of it with almost no downtime, reliability
and speed.
Surely it is not bug free and surely it is not able to cope with
any kind of user scenario.
The same, though, is true for kvm and virtualbox (just to name the
ones you named).
Maybe your use case is much closer to virtualbox's.

The ML is here to help, as much as possible.
If not and other tools are more suitable for your needs,
that's fine :)

Cheers,
Germano

Thanks Germano,

I'm running latest master branch taken from here:

|git clone git://github.com/xenserver/buildroot.git <http://github.com/xenserver/buildroot.git>|

as per:
https://github.com/xenserver/buildroot

If you could recommend me any good working branch I might be keen to try it.

btw. slightly off topic...
I've to admit that during last days I've run into so many issues that
almost gave up using Xen. But on the other hand I'm not sure if KVM is
any better.
For contrary, VirtualBox even if is headed towards desktop user, for
couple of VMs as I need at the moment could be a better solution for
me... It's sad to get to such conclusions, but given the time I've spent
troubleshooting and running from issue to issue... It makes me thinking
Xen is more in beta stage than real production one.

Regards,
Dawid
