[ovirt-users] 答复: 答复: 答复: How to Use VLAN?
Hi,All Does anybody know how to use VLAN in Hosted Engine 3.5 as new feature?(According to the http://www.ovirt.org/OVirt_3.5_Release_Notes, VLAN is a new function in Hosted Engine 3.5) -邮件原件- 发件人: users-boun...@ovirt.org [mailto:users-boun...@ovirt.org] 代表 Xie, Chao 发送时间: 2014年11月21日 9:35 收件人: Lior Vernia 抄送: users@ovirt.org 主题: [ovirt-users] 答复: 答复: How to Use VLAN? Hi, Lior Thanks for replying. Yesterday I tested VLAN successfully in the normal 3.5 environment. As the release Note, (http://www.ovirt.org/OVirt_3.5_Release_Notes), Hosted Engine 3.5 supports the new function of VLAN。 Is it meaning the rhevm logical network use VLAN ? If I am right, can you help to teach me how to use it? (I think it must be creating a VLAN manually before deploy hosted engine, then we should choose the vlan when deploying?) -邮件原件- 发件人: Lior Vernia [mailto:lver...@redhat.com] 发送时间: 2014年11月19日 16:50 收件人: Xie, Chao/谢 超 抄送: users@ovirt.org 主题: Re: 答复: [ovirt-users] How to Use VLAN?

Hello Xie, This is what leads me to believe that your DHCP server (which is in charge of allocating IP addresses) only receives non-tagged traffic. Is it possible you need to configure other ports to pass the VLAN-tagged traffic?

I already configure the switch port as TRUNK mode and the vlan id is 1 (default value). Which switch port? Maybe the port(s) leading to your DHCP server aren't configured to allow traffic on this VLAN? ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] Jumbo Frames
I think it should be something like:
def addMTU(interface, mtusize):
mtu = interface.createElement('mtu')
add_attributes(mtu, 'size')
mtu.setAttribute('size', mtusize)
def main():
mtusize = os.environ.get('extnet_mtu')
if mtusize is not None:
doc = hooking.read_domxml()
addMTU(doc, mtusize)
hooking.write_domxml(doc)

Hmm, if an property does not already exist how does one add it ?
def replaceMTU(interface, newmtu):
mtu = interface.getElementsByTagName('mtu')[0]
if not mtu.hasAttribute('size'):
mtu.setAttribute('mtu size', newmtu)
def main():
newmtu = os.environ.get('extnet_mtu')
if newmtu is not None:
doc = hooking.read_domxml()
interface, = doc.getElementsByTagName('interface')
replaceMTU(interface, newmtu)
hooking.write_domxml(doc)
When I test this code it throws and error:
mtu = interface.getElementsByTagName('mtu')[0]
IndexError: list index out of range
so somehow I need to detect that element needs to be set.
Could you please post how the libvirt xml should look like after the
current hook (if it supported setting the mtu?
Thanks, Phil

works with:
engine-config -s
CustomDeviceProperties='{type=interface;prop={extnet_ovs=^[a-zA-Z0-9_
---]+(:[a-zA-Z0-9_ ---]+|)$;extnet_mtu=^[a-zA-Z0-9_ ---]+(:[a-zA-Z0-9_

Now just need to sort out the Python code ;)

Ah, it looks like I need to the MTU on the underlying vnet interface
therefore should be able to extend the hook to include mtu size=9000/.
Have tried to add an additional property using:
CustomDeviceProperties='{type=interface;prop={extnet_ovs=^[a-zA-Z0-9_
---]+(:[a-zA-Z0-9_ ---]+|)$};{extnet_mtu=^[a-zA-Z0-9_ ---]+(:[a-zA-Z0-9_
---]+|)$}};'
but it fails with the following error:
Cannot set value {type=interface;prop={extnet_ovs=^[a-zA-Z0-9_
---]+(:[a-zA-Z0-9_ ---]+|)$};{extnet_mtu=^[a-zA-Z0-9_ ---]+(:[a-zA-Z0-9_
---]+|)$}}; to key CustomDeviceProperties. Invalid syntax, custom device
properties specification should conform to
\{type=(disk|interface|video|sound|controller|balloon|channel|redir|console|rng|smartcard|watchdog);prop=\{((([a-z_A-Z0-9])+)=(([^;])*)(;(([a-z_A-Z0-9])+)=(([^;])*))*;?)?\}\}[;]?
I did try:
CustomDeviceProperties='{type=interface;prop={extnet_ovs=^[a-zA-Z0-9_
---]+(:[a-zA-Z0-9_ ---]+|)$};prop={extnet_mtu=^[a-zA-Z0-9_
---]+(:[a-zA-Z0-9_ ---]+|)$}};'
but that just gave me a new property of 'prop' :)
Any help appreciated please.
Thanks, Phil

Hello Dan:
We are using OVS for SFlow and OSPF functionality. You can see that the
bridge was correctly set:
ovirtmgmt: flags=4163UP,BROADCAST,RUNNING,MULTICAST mtu 9000
Very odd as OVS is unaware of whether its jumbo frames or not.
Thanks, Phil

Why do you use OVS at all? If you have VLANs, all you need is to tag the mgmt
traffic, and create a VM traffic VLAN with a different MTU. The bridge and
underlying NICs will have MTU=9000 and the VM bridge will have MTU=1500

Hello:
am really enjoying oVirt but have now hit an issue with iSCSI. As there is
only one NIC in the host I have had to enable an MTU of 9000 on ovirtmgmt.
Then have vNIC profiles on that interface which are using a custom hook for
Openvswitch. I have created a specific vLAN for iSCSI traffic and on the
initiator and targets have set their respective interface MTUs to be 9000.
When I connect to a LUN it is timing out straight away with a 1011 error. If
I drop the MTU back to 1500 all works okay. This is all fine on my other
KVM, non-oVirt, system so am wondering if I have missed a step ?

Hi,
just tried it too.
I was not successfull to reproduce, but the problem is that
the domain part of LDAPSecurityAuthentication is uppercase
as Cameron wrote.
In 3.4 it is OK when it's upper case - everything works OK,
but in 3.5 it's not.
I checked differences and something like this would be enough, Yair?

}
Ondra
Looks fine, but please email me in private a testing environment where I can
check that.
Thanks!
P.S:
Another option worth trying is simply remove and add the domain, but hey, if
you're already in 3.5, and removed the domain, why not use he generic ldap
provider?

Hello,
I upgraded to ovirt 3.5.0 and can no longer authenticate to IPA.
Starting up ovrit-engine the extension manager fails to properly load
the service that handles Kerberos/LDAP.
This is probably a bug, can you please execute the following and paste
result:
# PGPASSWORD=@PASSWORD@ psql -U engine -d engine -c select * from
vdc_options where option_name='LDAPSecurityAuthentication'
option_id |option_name | option_value| version
---++---+-
165 | LDAPSecurityAuthentication | example.org:GSSAPI | general
I replaced my domain name with 'example.org'
I thought it will be empty... and it contains valid value. Yair?
No, this is fine actually.
Any I truly suggest you try out the new provider... Much easier to resolve
any issue, current and future, including easier to debug.

[ovirt-users] Failure on last step of ovirt hosted engine
Hello, I am following the guide up and running with ovirt 3.5 but with iscsi and not glusterfs. On the last step (after I have already installed ovirt-engine in the vm) the script has stopped due to an error. So the ovirt hosted vm is not registered in the datacenter and iscsi storage is not seen by datacenter. I am trying to use ovirt gui to register it manually without luck. I also cannot add the iscsi storage domain to current datacenter because obviously it is already attached to another datacenter. Can someone tell me how to repeat the last step of the script? Thanks, Mario ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
