[ovirt-users] Move SHE to a LUN on another storage appliance

[Colin Coe]

Hi all

I'm decommissioning an old SAN that holds our DEV/TST RHV instance.

I'm following https://access.redhat.com/solutions/6529691 (How to move the
Hosted-Engine storage to a new storage domain) and I'm on step 9 (Make sure
that the self-hosted engine is shut down).

hosted-engine --vm-status is reporting:
hosted-engine --vm-status | grep -E 'Engine status|Hostname'
Engine status  : {"vm": "up", "health": "good",
"detail": "Up"}
Hostname   : rhvh01.example.com
Engine status  : {"vm": "down_unexpected", "health":
"bad", "detail": "unknown", "reason": "vm not running on this host"}
Hostname   : rhvh02.example.com

Even though the vm is definitely shut down.

The instructions say call Red Hat but its nearly 6PM and we only have
standard support for this environment.

Any ideas on how to resolve this? I'm not sure if it's a big issue but I
don't want to cause myself more problems later.

Thanks

[ovirt-users] Tags in Ovirt

[Colin Coe]

Hi all

I'm trying to dump out a list of all tags and the VMs attached. I need to
do this as I wrote an Ansible task to attach some VMs to some tags and
ended up removing other VMs from these tags which caused some issues.

I think I've fixed my problem but I want to take a backup of the tags and
attached VMs but using ovirt.ovirt.ovirt_tag_info I can't see how to list
all tags with the attached VMs.

I've tried various incantations like:
  - ovirt.ovirt.ovirt_tag_info:
  auth: "{{ ovirt_auth}}"
  name: 'veeam-tier*'
  fetch_nested: true
  nested_attributes:
  - vm
register: result

but all I get is:
ok: [localhost] => {
"result": {
"changed": false,
"deprecations": [
{
"msg": "The 'fetch_nested' and 'nested_attributes' are
deprecated please use 'follow' parameter",
"version": "3.0.0"
}
],
"failed": false,
"ovirt_tags": [
{
"description": "",
"href":
"/ovirt-engine/api/tags/4ebb9243-b133-40c9-b22e-03b3798415bf",
"id": "4ebb9243-b133-40c9-b22e-03b3798415bf",

"id": "0fd7a16a-82ca-4d13-a9ab-9646a41c58e6",
"name": "veeam-tier1",
"parent": {
"href":
"/ovirt-engine/api/tags/----",
"id": "----"
}
},
{

"name": "veeam-tier2",
"parent": {
"href":
"/ovirt-engine/api/tags/----",
"id": "----"
}
}
]
}
}

I'm using fetch_nested and nested_attributes as I couldn't get 'follow' to
work.

Any ideas?

Hi

I'm looking at whats involved in upgrading our Ansible Tower setup
(external database plus isolated node) to RHEL8.

Pretty sure what I want has to have v4.4 or above SDK.

Thanks

[ovirt-users] RHV/oVirt and Ansible Tower/awx

[Colin Coe]

Hey all

We've recently moved from RHV v4.3 to RHV v4.4SP1 (ovirt v4.5) and I'm
wanting to rebuild one of our application "clusters" (not HA, simply a
group of related nodes that run the application stack)

Ansible Tower is v3.8.5 and is running on RHEL7.

To further complicate matters, we've just gone from Arcserve UDP to Veeam
and Veeam for RHV.

As I need to ensure the new VMs are built with COW disks with backup
"incremental" enabled.  After a lot of mucking about I find I have to fully
qualify the Ansible module names (i.e. ovirt_diskl becomes
ovirt.ovirt.ovirt_disk) but this has uncovered the next problem.

The workflow on Ansible Tower server is failing with "ovirtsdk4 version
4.4.0 or higher is required for this module".

So how can I wedge the v4.4 ovirt SDK onto this RHEL7 Ansible Tower node?

Thanks

[ovirt-users] Re: struggling with 4.5.1 install

[Colin Coe]

Hey Chris

The 192.168.222.x address is a temporary address for the hosted engine
whale the installation completes.

Did you say "yes" to pausing the hosted engine during the install?

You should see something in the logs about being able to hit
https://your.hypervisor.name:6900/ovirt-engine or is it dying before that?

You mention DHCP, I'd strongly encourage configuring a static IP.  A bond
is also strongly recommended but it really depends on how critical this
oVirt installation is to you.

Hope this helps.

[ovirt-users] Re: Make QXL the default

[Colin Coe]

Hi all

I edited /etc/ovirt-engine/osinfo.conf.d/00-defaults.properties and added
the lines:
os.rhel_6x64.devices.display.protocols.value = spice/qxl
os.rhel_7x64.devices.display.protocols.value = spice/qxl
os.rhel_8x64.devices.display.protocols.value = spice/qxl

And its working now.  Is this OK or is there a better way to handle this?

Thanks

[ovirt-users] Make QXL the default

[Colin Coe]

Hey all

We've just updated to RHV4.4SP1 (aka 4.5) from v4.4 and now our ansible
workflows are failing with:
cannot run VM. Selected display type is not supported by the operating
system

The OS are RHEL6 and RHEL7 (no, I can't change this as the software stack
only works with these)

I couldn't find anything in the ansible ovirt collection to change from VGA
to QXL.

Any ideas on how I can make QXL the default instead of VGA?  Maybe a DB
change?

[ovirt-users] Cluster CPU Type

[Colin Coe]

Hi all

I'm just putting in some new servers to be used as hosts in RHV 4.3 (soon
to go to v4.4 or v4.5) but I'm having problems with the cluster CPU.

These are HPE DL360 Gen10 with "Xeon Gold 6338N".  Google tells me these
are "Ice Lake" but RHV complains unless I set the cluster CPU type to
"SandyBridge".

Is this expected?  What do I need to do to get these recognised as the
corect CPU type?

Thanks

[ovirt-users] Cluster and datacenter compatibility levels

[Colin Coe]

Hi all

I'm looking for a definitive answer on what each compatibility level means.

Specifically, I'm looking for:
- new features
- deprecated features
- removed features

We're on 4.3 so I'm looking for the info above on 4.4, 4.5 and 4.6

My main motivation is to ensure we don't lose SPICE support.

We actually use RHV and I logged a case with Red Hat GSS but couldn't get
the info I was after.

[ovirt-users] Re: no QXL ?

[Colin Coe]

OK, so how will I present secure VMs (i.e. VMs that live in secure,
protected networks) at unsecure locations once SPICE is gone?  VNC and RDP
connect to the VM itself.  SPICE connects to a TLS port on the hypervisor
which means we never expose the VM to the end users network and we have a
small number of devices (hypervisors) to protect.

I'm happy to take suggestions.

[ovirt-users] Re: no QXL ?

[Colin Coe]

For us, SPICE lets us present VMs in secure networks to unsecure
locations.  RDP and VNC will not work for us.

I didn't want to rant but why Red Hat drops useful features is beyond me.
First Satellite 5 (Spacewalk), GlusterFS, not RHV.  Yep, we've been a RHV
customer since RHEV v2.2 days.  SPICE was the compelling feature then and
remains so.

My 2 cents

[ovirt-users] Commvault

[Colin Coe]

Hi all

My workplace is considering replacing Arcserve (which has been terrible)
with Commvault.

Our virtualisation is a mix of about 95% RHV and 5% HyperV.  We have a
handful of physical servers, a 50/50 mix of Windows and RHEL.

We run dual hot data centers, and want to backup locally (disk to disk)
then replicate to the other data center.  Cloud is off the table.

Anyone have any experience with Commvault?  War stories?

Happy to be pointed at other alternatives.

Thanks

[ovirt-users] SPICE proxy behind nginx reverse proxy

[Colin Coe]

Hi all

As per $SUBJECT, I have a SPICE proxy behind a reverse proxy which all
external VDI users are forced to use.

We've only started doing this in the last week or so but I'm not getting
heaps of reports SPICE sessions "freezing".  The testing that I've done
shows that a SPICE session that is unattended for 10-15  minutes hangs or
freezes.  By this I mean that you can't interact with the VM (using SPICE)
via mouse or Keyboard.  Restarting the SPICE session fixes the problem.

Is anyone else doing this?  If so, have you noticed the SPICE session
freezes?

Thanks in advance

[ovirt-users] Backup software recommendations

[Colin Coe]

Hi all

I'm looking for recommendations for backup software.  It needs to handle
physical and virtual Linux and Windows, RHV and Hyper-V.

It doesn't have to be open source and it doesn't have to be free.

The main features we need are:
- disk to disk backups
- inter-site replication with rate limiting
- be able to handle Linux thin volumes (think RHGS)
- support BMR ans granular file / directory restore
- correctly handle Windows VSS
- support RHEL point releases as soon as they are released

I'm as much after "stay away from" as recommendations.

We currently use Arcserve UDP and it is ... well ... sub optimal

Thanks in advance

I agree

We've already had the situation of VMs being created in a data domain that
was intended for export purposes only.  I like things kept separate.

[ovirt-users] ISO and Export domains deprecated

[Colin Coe]

Hi all

I'm trying to understand how ISO and Export domains going away  is going to
affect us.

We have four RHV instances:
- Prod DC1 (RHV4.1)
- Prod DC2 (RHV4.1)
- DEV (RHV4.3)
- TEST (RHV4.3)

Prod DC1, DEV and TEST all share export and ISO domains.

Prod DC2 is remote and currently has its own ISO and Export domains.

When ISO and Export domains go away, can I still share ISO domains between
the RHV instances?

Thanks

[ovirt-users] Re: Users and VM permissions matrix

[Colin Coe]

Hi

At the moment I'm just trying to work out how to get the info but
ultimately it needs to be a matrix of users across the top, VMs down and
print the role where the two intersect.

Thanks

[ovirt-users] Users and VM permissions matrix

[Colin Coe]

Hi all

I've been tasked with creating a matrix of users/groups and VMs so we can
easily see who has access to what (via SPCIE console).

Google has given me a couple of hints but I can get it over the line.

---
users_service = connection.system_service().users_service()
users = users_service.list()

for user in users:
username = user.user_name.split('@')[0]

# Follow the link to the permissions of the user:
perms = connection.follow_link(user.permissions)
for perm in perms:
if perm.vm:
print(username)
permissions_service =
connection.system_service().permissions_service()
print(perm.vm.id)
---

The problem is with permissions, the output from above is:
---
user1
1b645daf-de26-4f33-9e3b-6a12eadd4618
user2
9c79e763-f78d-4bf9-b8ca-20fe197fd80c
user3
f9d00b30-8003-41c3-95a1-10e0c452fa63
user4
1bbadf96-ef95-4ece-b5f3-1fa112aa3571
user5
e9085627-324e-48d3-bc04-52ff7798ddd0
---

I can't work out how to get the actual permissions rather that the ID.

Any ideas?

Thanks

[ovirt-users] Re: Find MAC for VM

[Colin Coe]

Ignore, I was missing [0].

Working solution is:
---
nics_service = vms_service.vm_service(vm.id).nics_service()
nic = nics_service.list(query={"search": "name=nic1"})[0]

print('host ',sys.argv[2],' {', sep='')
print('hardware ethernet ',nic.mac.address,';', sep='')
print('fixed-address x.x.x.x;')
print('option host-name "',sys.argv[2],'";', sep='')
print('}')
---

Thanks!

[ovirt-users] Re: Find MAC for VM

[Colin Coe]

Hi Joey

Thank you, I'm further along now.  I need to get the MAC address of the
interface.

I've now got:
---
nics_service = vms_service.vm_service(vm.id).nics_service()
nic = nics_service.list(query={"search": "name=nic1"})
#nic = nics_service.list(search='name=nic1')[0]

print('host ',sys.argv[2],' {', sep='')
print('hardware ethernet ',nic.mac.address,';', sep='')
print('fixed-address x.x.x.x;')
print('option host-name "',sys.argv[2],'";', sep='')
print('}')
---

In RHV 4.3, I can use nic.mac.address but that doesn't seem to work here.

Any ideas how to get that last puzzle piece?

Thanks

Hi Joey

The error I get is:

  File "createVmFromTemplate.py", line 40, in 

nic = nics_service.list(search='name=nic1')[0]

TypeError: list() got an unexpected keyword argument 'search'


The SDK versions I have are:

- python-ovirt-engine-sdk4-4.1.7-1.el7ev.x86_64

[ovirt-users] Find MAC for VM

[Colin Coe]

Hi all

I've got the following Python snippet which works fine under 4.3 but I need
it to work under 4.1 as well.
---
nics_service = vms_service.vm_service(vm.id).nics_service()
nic = nics_service.list(search='name=nic1')[0]
---

Under 4.1, it barfs on "nics_service.list(search='name=nic1')[0]".

What do I need to do to make it work under 4.1?

[ovirt-users] Re: Spice console very poor performance for Windows 10 vm

[Colin Coe]

Hi

We're struggling with this also.  We're running RHV 4.3 in our development
environment and have found that he latest client tools in conjunction
with v0.19
of the Windows 10 driver

has
made a big difference to performance.  Additionally, we have
/etc/ovirt-engine/osinfo.conf.d/20-overload.properties with:
os.windows_10.devices.display.vramMultiplier.value = 8
os.windows_10x64.devices.display.vramMultiplier.value = 8

This new driver isn't perfect though and we've found that various things
stop working after a couple of days. These include screen auto resizing and
also the mouse/keyboard gets captured when the screen auto resize stops
working.  Our clients are typically dual screen, each at 2560x1440.

We're going live with a new environment in about 4 months which will
include 140+ VDI Windows 10 VMs so we're very keen to get this sorted.

 I'm not familiar with oVirt interface but it shouldn't be hard if
 you have access to the host.

 # virsh edit $vm-name

 switch what you have in graphics to:

[Colin Coe]

Hi all

I've installed the v0.19 driver on a couple of test VMs.  Particularly in
multi-monitor VMs, this version is significantly better than what's
provided in the RHV Tools 4.3-6 ISO image.

I've opened an RFE with GSS to have v0.19 added to the RHV tools ISO.

Thanks

Hi Victor

The SPICE server is
rpm -q spice-server
spice-server-0.14.0-6.el7_6.1.x86_64

On the VM we're using SPICE QXL.

Looks like
https://www.spice-space.org/download/windows/qxl-wddm-dod/qxl-wddm-dod-0.19/spice-qxl-wddm-dod-0.19.zip
has the performance fixes you mentioned.

Any ideas if/when this will be shipped with/on the RHV Tools ISO?

Thanks

[ovirt-users] SPICE and Windows 10

[Colin Coe]

Hi all

We've just updated our dev environment from 4.1 to RHV 4.3 and found that
while a lot better, Windows 10 under SPICE still isn't great.

We're running dual screen VMs at 2560x1440 resolution.  The Windows login
screen is particularly bad although once logged in it gets better but not
great.  The benchmark here is Windows 10 vs Windows 7 VMs.

We've gone into settings / advanced and set "configure for best
performance".  Latest RHV tools (4.3-6) are installed.  We've also created
"/etc/ovirt-engine/osinfo.conf.d/20-overload.properties" containing:
os.windows_10.devices.display.vramMultiplier.value = 4
os.windows_10x64.devices.display.vramMultiplier.value = 4

When we set the multiplier to 8, as recommended in another thread,
ovirt-engine fails to restart.

I know there have been a few threads on this but I'd like to ask what is
the advice for RHV/oVirt 4.3 to make Windows 10 faster?  VDI on RHV makes
up an important part of what we do and RDP, VNC, etc are not an option.

Thanks

Add your nodes to oVirt then add your storage.  Don't try to manually
control the storage, let oVirt do that.

I'd like to prevent disabled users from appearing in the Users or

include = 

vars.domain = example.com
vars.user = CN=user,OU=Restricted,OU=Users,OU=PROD,DC=example,DC=com
vars.password = passsword

pool.default.auth.simple.bindDN = ${global:vars.user}
pool.default.auth.simple.password = ${global:vars.password}
pool.default.serverset.type = srvrecord
pool.default.serverset.srvrecord.domain = ${global:vars.domain}

[ovirt-users] Private VLANs

[Colin Coe]

Hi all

We running RHEV 4.1.10 on HPE Blade servers using Virtual Connect which
talk to Cisco switches.

I want to implement private VLANs, does the combination of oVirt + Cisco
switches + HPE Virtual Connect work with private VLANs?

To be clear, I want to have a couple of logical networks (i.e. VLANs) where
the nodes in that VLAN cannot talk directly but must go through the
router/firewall.

[ovirt-users] Host affinity rule

[Colin Coe]

Hi all

I suspect one of our hypervisors is faulty but at this stage I can't prove
it.

We're running RHV 4.1.7 (about to upgrade to v4.1.10 in a few days).

I'm planning on create a negative host affinity rule to prevent all current
existing VMs from running on the suspect host.  Afterwards I'll create a
couple of test VMs and put them in a positive host affinity rule so they
only run on the suspect host.

There are about 150 existing VMs, are there any known problems with host
affinity rules and putting 150 or so VMs in the group?

This is production so I need to be careful.

[ovirt-users] Non-RHEL RPMs gone after RHV-H upgrade

[Colin Coe]

Hi all

We're running RHV 4.1.6.  Yesterday I upgraded the RHV-H nodes in our DEV
environment to 20180102 and found that all the non-RHEL RPMs are now gone.
Their associated config files in /etc are still there.  The RPMs in
question were from HPE SPP plus a monitoring system client (Xymon).

I had thought that non-RHEL RPMs would persist after a host upgrade.

Am I wrong on this?

Re: [ovirt-users] V4.1 questions

[Colin Coe]

Hi Ryan and thanks for the quick reply.

This is an entirely new system, no VM, no nothing.  This was built for
testing v4.1.  I'll log a case with GSS on this if it  is not normal.

Bit confiused, so what do I need to do for the Installation -> Check for
Upgrades to work in RHV-M?  I'm using an old RHEV-H 7.1 image for the
hypervisors so there should definitely be an upgrade available.

Also, any thoughts on the webUI timeout?

Thanks again

[ovirt-users] V4.1 questions

[Colin Coe]

Hi all

We're in the process of upgrading from RHEV 3.5 to 4.1.5 and I have a
couple of questions.

RHV 4.1.5 takes between 10-15 minutes to become usable after a service
restart, is this expected or is something wrong with our environment?

The webUI seems to timeout and go back to the logon page after a very short
time.  Can this behavior be changed?

Lastly, the RH318 course book states that to upgrade a RHEV-H node via
RHEV-M, you need to install the "rhev-hypervisor7" package on the RHEV-M
node.  Is this still correct?

Thanks

Re: [ovirt-users] Adding host for the first time - Power Management?

[Colin Coe]

If you log in to the blade enclosure OA (onboard administrator) via the web
interface:
- Expand Enclosure Information
- Expand Device Bays
- Expand the required server
- Click on iLO
- Click Web Administration link (a new browser window will appear)
- Expand Administration
- Select User Administration

At this point you should be able to add, remove, edit users including
resetting passwords and defining permissions.

Re: [ovirt-users] Good practices

[Colin Coe]

Hi

I just thought that you'd do hardware RAID if you had the controller or
JBOD if you didn't.  In hindsight, a server with 40Gbps NICs is pretty
likely to have a hardware RAID controller.  I've never done JBOD with
hardware RAID.  I think having a single gluster brick on hardware JBOD
would be riskier than multiple bricks, each on a single disk, but thats not
based on anything other than my prejudices.

I thought gluster tiering was for the most frequently accessed files, in
which case all the VMs disks would end up in the hot tier.  However, I have
been wrong before...

I just wanted to know where the OS was going as I didn't see it mentioned
in the OP.  Normally, I'd have the OS on a RAID1 but in your case thats a
lot of wasted disk.

Honestly, I think Yaniv's answer was far better than my own and made the
important point about having an arbiter.

Thanks

Re: [ovirt-users] Good practices

[Colin Coe]

1) RAID5 may be a performance hit

2) I'd be inclined to do this as JBOD by creating a distributed disperse
volume on each server.  Something like

echo gluster volume create dispersevol disperse-data 5 redundancy 2 \
$(for SERVER in a b c; do for BRICK in $(seq 1 5); do echo -e
"server${SERVER}:/brick/brick-${SERVER}${BRICK}/brick \c"; done; done)

3) I think the above

4) Gluster does support tiering, but IIRC you'd need the same number of SSD
as spindle drives.  There may be another way to use the SSD as a fast
cache.

Where are you putting the OS?

Hope I understood the question...

Thanks

[ovirt-users] EMC Unity 300

[Colin Coe]

Hi all

We are contemplating moving away from our current iSCSI SAN to Dell/EMC
 Unity 300.

I've seen one thread where the 300F is problematic and no resolution is
posted.

Is anyone else using tis with RHEV/oVirt?  Any war stories?

Re: [ovirt-users] Can't virtualize CentOS 7.x on oVirt 3.6

[Colin Coe]

Hi

I see this also and I've logged a bug with Red Hat support on it.  I have
found though that sometimes, if you wait long enough (i.e. approx 22
minutes) it will eventually boot.

The other thing I've found is that if you change from SPICE to VNC, the
problem goes away completely.

Thanks

Re: [ovirt-users] Export VM from oVirt/RHEV to VMWare

[Colin Coe]

Hi Zach

Thanks for the helpful suggestion.  I was hoping to avoid this but it looks
like my only option.

Thanks again

Re: [ovirt-users] Export VM from oVirt/RHEV to VMWare

[Colin Coe]

Hi all

The VM in question is a Windows 2008R2 server.  Any one have any thoughts
on this?

Thanks

[ovirt-users] Export VM from oVirt/RHEV to VMWare

[Colin Coe]

Hi all

We run RHEV exclusively and I need to export a guest to one of our vendors
for analysis.

The vendor uses VMWare.  How can I export a VM in OVF format out of RHEV
v3.5.8?

Re: [ovirt-users] [ovirt 3.6] Logical network not working

So is the problem getting traffic between two different VLANs working?  If
so, have you double checked your routing?

Re: [ovirt-users] [ovirt 3.6] Logical network not working

[Colin Coe]

I've been using RHEV with HP virtual connect (currently C7000 with
Flex10/10D, previously C3000 With Flex10) for years now, mostly without
problems.

The switch port that connects the virtual connect environment to the rest
of your network, is it configured as a trunk and is VLAN 828 allowed?

IIRC, a previous (recent) post stated that going from OVS to legacy was not

Re: [ovirt-users] one export domain two DC

[Colin Coe]

Not sure about 4.0, but We have RHEV 3.5 and RHEV 3.6 sharing the same
export domain.  Caveat is it can only be attached to one DC at a time.

Re: [ovirt-users] [oVirt 4.0] Is it possible to access oVirt through a reverse proxy

[Colin Coe]

Hi all

I've logged case 01662585 with GSS.

I see that RHEV 4.0 beta is in the customer support portal, I'm going to
see if we can upgrade our current DEV RHEV environment to 4.0 BETA so we
can start testing early.

Thanks

Re: [ovirt-users] [oVirt 4.0] Is it possible to access oVirt through a reverse proxy

[Colin Coe]

Hi all

If this is correct, it is a massive problem for us.  We're still on RHEV
v3.5 ATM but have plans to move to RHEV v4 when it looks production ready.

Many of our users are external parties that access the RHEV user portal
externally via a (Juniper) reverse proxy appliance.  The RHEV user
portal URL gets rewritten to the URL of the Juniper appliance.

Should I file a bug on this, or an RFE?

Thanks

Re: [ovirt-users] oVirt/RHEV and HP Blades and HP iSCSI SAN

[Colin Coe]

HI Dan

As this is production, critical infrastructure large downtime is not
possible.  We have a hardware refresh coming up in about 12 months so I'll
have to wait until then.

I recall asking this of GSS quite some time ago and not really getting too
helpful an answer

We use a combination of Cisco C4500-X (core/distribution) and C2960-X
(access) switches.  The SAN units connect into the C4500-X switches (32 x
10Gbps ports).

Thanks

Re: [ovirt-users] oVirt/RHEV and HP Blades and HP iSCSI SAN

[Colin Coe]

Hi Fernando

The network is pretty much cast in stone now.  I even if I could change it,
I'd be relucant todo so as the firewall/router has 1Gb interfaces but the
iSCSI SANs and blade servers are all 10Gb.  Having these in different
subnets will create a 1Gb bottle neck.

Thanks

Re: [ovirt-users] oVirt/RHEV and HP Blades and HP iSCSI SAN

[Colin Coe]

Hi Dan

I should have mentioned that we need to use the same subnet for both iSCSI
interfaces which is why I ended up bonding (mode 1) these.  Looking at
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Administration_Guide/sect-Preparing_and_Adding_Block_Storage.html#Configuring_iSCSI_Multipathing,
it doesn't say anything about tying the iSCSI Bond back to the host.  In
our DEV environment I removed the bond the iSCSI interfaces were using and
created the iSCSI Bond as per this link.  What do I do now?  Recreate the
bond and give it an IP?  I don't see where to put an IP for iSCSI against
the hosts?

Lastly, not using jumbo frames as where a critical infrastructure
organisation and I fear possible side effects.

Thanks

[ovirt-users] oVirt/RHEV and HP Blades and HP iSCSI SAN

[Colin Coe]

Hi all

We run four RHEV datacenters, two PROD, one DEV and one TEST/Training.
They are all  working OK but I'd like a definitive answer on how I should
be configuring the networking side as I'm pretty sure we're getting
sub-optimal networking performance.

All datacenters are housed in HP C7000 Blade enclosures.  The PROD
datacenters use HP 4730 iSCSI SAN clusters, each datacenter has a cluster
of two 4730s. These are configured RAID5 internally with NRAID1. The DEV
and TEST datacenters are using P4500 iSCSI SANs and each datacenter has a
cluster of three P4500s configured with RAID10 internally and NRAID5.

The HP C7000 each have two Flex10/10D interconnect modules configured in a
redundant ring so that we can upgrade the interconnects without dropping
network connectivity to the infrastructure. We use fat RHEL-H 7.2
hypervisors (HP BL460) and these are all configured with six network
interfaces:
- eno1 and eno2 are bond0 which is the rhevm interface
- eno3 and eno4 are bond1 and all the VM VLANs are trunked over this bond
using 802.1q
- eno5 and eno6 are bond2 and dedicated to iSCSI traffic

Is this the "correct" way to do this?  If not, what should I be doing
instead?

Thanks

Re: [ovirt-users] Can't start VM after shutdown

[Colin Coe]

Yeah, that looks like the fix Red Hat GSS came up with.  Note that is only
online snapshots that we've seen the problem with, never offline but YMMV.

What version of oVirt are you running?  We're running RHEV 3.5.7 in prod
and test environments but 3.6.5 in dev and we've not had a re-occurrence of
this problem in dev since moving to 3.6.x

Hi Marek and thanks for the reply.

Can the "Connect Automatically" check box on the User Portal login page be

Hi all

Is there a setting for globally turning on the console option of "Open in
Full Screen"?

Also, can the "Connect Automatically" be permanently and globally disabled?

We're on RHEV 3.5.7

Re: [ovirt-users] Disks Illegal State

We're seeing this in RHEV 3.5 with snapshot management on VMs with multiple
disks.  It would be awesome to have a "fsck" type script that could be run
daily which reports on any problems with the snapshot disks.

Re: [ovirt-users] VM has been paused due to no Storage space error.

[Colin Coe]

Ahh, we've seen this as well in RHEV and have wondered what was going on.
A better message would be good.

[ovirt-users] Guest/User permissions

Hi all

I've been asked to produce a matrix of guests (VMs) and the users who have
rights on them.

Just trying to save myself some effort and see if anyone's already done
this and is willing to share?

Re: [ovirt-users] All snapshots read only

[Colin Coe]

Hi and thanks for the response

1) RHEV v3.5.7
2) The VM was powered on and running fine when the snapshot was taken (this
is done through cron)
3) The snapshot was created via a Python oVirt SDK script
4) The status is showing "OK" for both the VM's disks and the snapshots
disks.

As a test, I took a snapshot of another VM that was running OK.  When the
snapshot was completed, the delete buttn was greyed out.

I turned the original server off and found that the snapshot button was no
longer greyed out.  When I turned the server back on, the delete button is
greyed out again.

My API script that creates the snapshots also deletes the snapshot from 7
days ago.  I see that the last successfully deleted was on Jan 26.  We
upgraded from v3.5.0 to v3.5.7 on Jan 24.  Nothing changed on the server
after Jan 24 so I'm a bit stumped.

Thanks

I run RHEV not oVirt so I don't see this but I suspect  it's a feature
request that I put in to be notified when a Windows VM is running an old
version of the RHEV tools/agent.

Re: [ovirt-users] All snapshots read only

[Colin Coe]

I've just checked our dev and test RHEV instances (both also on v3.5.7),
and found that the overnight snapshot script is working correct and is
deleting old snapshots.  A quick check of other VMs shows their snapshots
do not have the delete button greyed out.

I'm thinking there's something screwy with this prod RHEV instance.

Re: [ovirt-users] Consolidating LUNs in iSCSI storage domain

[Colin Coe]

Hi and thanks for the response

Is there any way that this could be done without putting the entire
datacenter (and I assume shutting done all the VMs) into maintenance mode?

I was thinking along the lines of:
- Put all hosts except for the the SPM into maintenance mode
- Determine which LUNs match to the "/dev/dm-*" devices that the three I
want to remove (rhev-data01, rhev-data02, rhev-data03)
- Determine which LUN matches the "/dev/dm-*" devices that I want to keep (
rhev-data04)
- pvmove rhev-data01 rhev-data04
- pvmove rhev-data02 rhev-data04
- pvmove rhev-data03 rhev-data04

The pvmove commands above for illustration only, I know thats not how the
LUNs would be called.

Does that look like it would work?

Thanks

I've created a GSS case for this: 01578873.  Attached to the case is a
rhevm-log-collector for the affected prod RHEV and a rhevm-log-collector
for the dev RHEV which is not affected.

[ovirt-users] Consolidating LUNs in iSCSI storage domain

[Colin Coe]

Hi all

In one of our RHEV setups (v3.5.4) the iSCSI storage domain consists of
four LUNs.  (full details in the attached text file).

I want to consolidate all the data on LUNs
iqn.2003-10.com.lefthandnetworks:iscsi:341:rhev-data01
qn.2003-10.com.lefthandnetworks:iscsi:453:rhev-data02
iqn.2003-10.com.lefthandnetworks:iscsi:518:rhev-data03
to LUN
iqn.2003-10.com.lefthandnetworks:iscsi:687:rhev-data04

Is this possible?

Thanks

[ovirt-users] All snapshots read only

[Colin Coe]

Hi all

I've just noticed that all VM snapshots on one of our prod RHEV setups have
gone read-only (i.e. delete is greyed out).

Has anyone else seen this?

Is there an easy fix for this?  We have a bunch of VVMs being snapshotted
nightly with snapshots being deleted after 7 days.

Thanks

Re: [ovirt-users] VDI non-persistant desktops

[Colin Coe]

Hi and thanks for the reply.

Not really what we're after.  We want the stateless VMs but we want to be
able to work on the template (patch, install addtional software, etc) and
have those changes flow through to the existing VMs based on these
templates.  In addition, when the VMs are refreshed based on the updated
template, we need the MAC addresses to persist (as we define all our leases
in DHCP).

[ovirt-users] LUN Resizing

[Colin Coe]

Hi all

Just wondering if http://www.ovirt.org/Features/LUN_Resize made it into
oVirt 3.6 and if it will be in RHEV-M 3.6?

[ovirt-users] VDI non-persistant desktops

[Colin Coe]

Hi all

We're using RHEV 3.5.7 and have about 40 desktop VMs that are all clones
from a single original.

In the very beginning we used desktop pools but this was torn down when we
started getting "The trust relationship between this workstation and the
primary domain failed" error messages.

We use DHCP for all desktops however every VM is defined on the DHCP server
and unknown MACs are rejected.

I'd like to revisit desktop pools but I'd like to know if other are using
this and what their experiences have been.

Kind of thing I'd like to know is
- how is patching done
- what is the performance like
- what tuning if any is done on the desktops
- GPO vs LPO

Any comments?

Thanks

Re: [ovirt-users] Python API question

[Colin Coe]

Hi again all

I've just noticed that the snapshot status appears not to update.

Consider the code below:
---
api.vms.get(VM_NAME).snapshots.add(params.Snapshot(description=SNAPSHOT_NAME,
vm=api.vms.get(VM_NAME), persist_memorystate=True))

# Wait for snapshot to finish
snap = api.vms.get(name=VM_NAME).snapshots.list()[-1]
while (snap.get_snapshot_status() == 'locked'):
   print "Waiting for snapshot creation to finish (status is %s)" %
snap.get_snapshot_status()
---

What I find is that even though the WebUI reports the snapshot is created,
snap.get_snapshot_status() still reports 'locked'.

I'm using RHEV 3.5.7 with RHEL-H 7.1 hosts with vdsm-4.16.30-1.el7ev.x86_64.

Am I misunderstanding how this works or have I found a bug?

Thanks

[ovirt-users] Default profile

[Colin Coe]

Hi all

Is it possible to set the default profile (on the User Portal login page
and for all users) to the AD domain name rather than "Internal"?

Also, can the "Connect Automatically" check box (on the User Portal login
page) be set to default to un-checked?

Running RHEV 3.5

Thanks

Re: [ovirt-users] Default profile

[Colin Coe]

Hi and thanks for the quick response!

The profile is only remembered in the browser cache.  Most of our VDI users
use IGEL thin clients in SPICE appliance mode.  This means they have to
remember to set the profile every time they login. For our remaining users
connecting from standard PCs if their profile deleted (the "help" desk's
first move if there is a problem on the PC) or if they connect from a
difference PC they also have to set the profile.

I'll put in a request to GSS for this as a feature request.

Thanks again

[ovirt-users] Python API question

[Colin Coe]

Hi all

I've written a Python script to take nightly snapshots of VMs which are
kept for x days.  After x days the snapshot is deleted.

I can't work out how to wait for the snapshot deletion to complete.  I know
how to do it for creating the snapshot but I've not been able to get it
right for the deletion.


api.vms.get(VM_NAME).snapshots.add(params.Snapshot(description=SNAPSHOT_NAME,
vm=api.vms.get(VM_NAME), persist_memorystate=True))
  while api.vms.get(VM_NAME).status.state == 'image_locked':
  sleep(1)

Any ideas?

Thanks
