Can System VMs be migrated?
Hi folks,
I was wondering, can we migrate systems vms from a host to another one in
the same cluster?

Somesh Naidu and others,
Now I understand the problem. But, that code does not make much sense to me.
As I said before, the “system.vm.use.local.storage” parameter was already
set to false. Therefore, the SQL command “select id,name,use_local_storage
from disk_offering where system_use=1” returns:
id name use_local_storage
7 System Offering For Software Router false
8 System Offering For Elastic LB VM false
9 System Offering For Secondary Storage VM false
10 System Offering For Console Proxy false
30 System Offering For Internal LB VM false
All as expected.
The problem happens because of the method
“com.cloud.hypervisor.xen.resource.XcpOssResource.createPatchVbd(Connection,
String, VM)” that was overwritten. Someone, for some odd reason changed the
behavior of the default implementation that is found on
“com.cloud.hypervisor.xen.resource.CitrixResourceBase”.
I tested the commands that are in
“com.cloud.hypervisor.xen.resource.CitrixResourceBase” and they work just
fine for XAPI (XCP). Those are the commands used in XS environments.
IMHO the
“com.cloud.hypervisor.xen.resource.XcpOssResource.createPatchVbd(Connection,
String, VM)” method should be removed and the behavior of the parent class
should be kept, hence it works properly. Moreover, that overwritten method
does not respect the “system.vm.use.local.storage” parameter.
Thus, to the best of my knowledge (
http://pt.slideshare.net/xen_com_mgr/xpus13-pavlicek), at the end XAPI and
XS are almost the same, hence the XAPI in bundled into xenserver.
Should I open a bug report(is it really a bug or something intentional?)?

RE: Can System VMs be migrated?
Posted by Somesh Naidu <So...@citrix.com>.
Ok. I don't know what the expected behavior for XCP is (though I believe shared storage for system VMs should work on XCP as well).
If you were using XenServer then the way it works is that depending on the value (true/false) set for global config system.vm.use.local.storage, CS will set the storage type in the system service offering during mgmt. bootstrap.
When I say system offering I refer to the records returned by the query - select id,name,use_local_storage from disk_offering where system_use=1;

Somesh

Somesh Naidu,
I am using the 4.3.0 version.
I am using Xen hypervisor with XAPI (old XCP) packages over Debian 7.4
I did not understand what you mean with “in the system offerings” . The
primary storage of the clusters are NFS servers.

RE: Can System VMs be migrated?
Posted by Somesh Naidu <So...@citrix.com>.
Rafael,
What version of CS are you using? I have a 4.3 and a 4.5 environment with XS/VMware/KVM hypervisors and on all of them, the system VMs are being created on shared primary storage.
Can you check what storage type is set in the system offerings?
Regards,
Somesh

Subject: Re: Can System VMs be migrated?
Marcus, the parameter “system.vm.use.local.storage” was already set to
false. That parameter does not make any sense to me; it seems that it is
not used, at least for Xen.
Abhinandan Prateek, I did not configure it erroneously. I configured NFS
storage to store users VMs (primary storage), I am not using local storage
for anything, but sadly I was forced to create a local SR into every host.
I had exchanged some emails about that in the users list a while ago:
http://mail-archives.apache.org/mod_mbox/cloudstack-users/201309.mbox/%3CCAG97radxdiUaim7-W5nw-BAcvTFV0MgD6RJzB64=ueRvM89V0g@mail.gmail.com%3E
The problem seems to be here:
com.cloud.hypervisor.xen.resource.XcpOssResource.createPatchVbd(Connection,
String, VM)
That class do not use the parameter “system.vm.use.local.storage”, it
forced us to add a local SR in the host. Then it deploys the systemvm-vdi
into that “_host.localSRuuid”.
http://fossies.org/dox/apache-cloudstack-4.4.2-src/XcpOssResource_8java_source.html
Is that behavior expected? I have lived with that since CS 4.1.1 (I am
using 4.3.0) and it seems to be the same in 4.4.

Re: Can System VMs be migrated?
Posted by Abhinandan Prateek <ab...@shapeblue.com>.
While creating a zone you can configure the use of local storage. It seems you configured it erroneously.
In 4.3 as per my knowledge live vm migration with local storage is broken. Use it in 4,5 it works I have tested it.
If you do not want to use local storage make sure you turn it off while creating the zone.

Re: Can System VMs be migrated?
Posted by Rafael Weingartner <ra...@gmail.com>.
Well,
There is a button, take a look at the SS I took:
http://postimg.org/image/5sr7yxyud/
I am curious, why does the CS allocate system VMs’ VDI on local SR on Xen
hypervisor? Why not use the primary storage of the cluster in which the
host is in?
I looked at the code, and it is hard coded there, Xen hosts have to have a
local SR, otherwise you cannot add them into CS (first time I saw that I
found it very weird, I even sent an email about it, but did not get any
reply).
That does not seem to happen with other hypervisors.
Now that you mentioned the maintenance mode, I noticed that system VMs are
not being migrated when I put its host in maintenance, I thought that was a
normal behavior (weird one but normal, given that those VMs are using the
local SR of the Xen hypervisor).

How do you migrate systemVM’s in UI?
If you just put the host, where the systemVM’s are running, into
“maintenance” mode, then you may have hit this bug which was fixed in
4.4.0: https://issues.apache.org/jira/browse/CLOUDSTACK-5660

Update:
The UI may not be working because it uses the command "migrateSystemVm",
instead of "migrateVirtualMachineWithVolume".

That is the answer I wanted to hear. If we can migrate system VMs, why are
the systems VMs’ VDI allocated in the local SR on Xen hypervisor?
It is not possible to migrate those system VMs, hence they are using a
local SR.
