Issue in xenserver VM packet loss
Hi I have ACS 4.2 with Advance Networking setup. In one of my cluster group I have Xenserver 6.2 in this all the VM users complains Network issue. Where I could see packet loss so I generated the sever status report and uploaded to taas.citrix.com where they recommended to below pasted defect. OVS Flow Eviction Threshold Exceeded Issue detected on: xen13.sjc.xxx.net, xen14.xxx.net Description: When the flow eviction threshold is exceeded packet loss can occur and network performance can be impacted Citrix Recommendations: Please follow the below link which suggests increasing flow eviction threshold or if that has been maximized then rolling back to bridge to resolve issues. http://support.citrix.com/article/CTX140764 Extra Information: Bridge Name + ' ' + Flow Eviction Threshold + ' ' + Flow Value + ' ' + Packets Lost xenbr5 1000 2249 1128814 ; Bridge Name + ' ' + Flow Eviction Threshold + ' ' + Flow Value + ' ' + Packets Lost xenbr5 1000 1313 0 Severity: Medium Category: Networking I that ok to switch ovs to *xe-switch-network-backend bridge mode.* *Thanks,* *Keerthi*

database tag query getting delayed indefinitely
Hi all, While setting a new ACS installation using centos6.6 and 4.4.2 (I have several fully functioning ones running ubuntu12.04 + 4.3.0) I'm finding out that filtering VMs with tags hangs the mysql database. Whenever an API query like this is run: apiKey=REDACTEDcommand=listVirtualMachinesisrecursive=truelistall=trueresponse=jsontags[0].key=chef_envtags[0].value=fqa1zoneid=30c4a514-402c-4413-a3fc-c65450a98f55signature=REDACTED a query in the database like this is seen: SELECT DISTINCT(user_vm_view.id) FROM user_vm_view WHERE user_vm_view.account_type != 5 AND user_vm_view.state != 'Destroyed' AND user_vm_view.display_vm = 1 AND ( ( user_vm_view.tag_key = _binary'chef_env' AND user_vm_view.tag_value = _binary'fqa1' ) ) AND user_vm_view.removed IS NULL ORDER BY user_vm_view.id ASC LIMIT 0, 500 ; This should return 2 items, and doing this query manually with around 5 of the where constrictions returns the values in less than a second. Running the command above might take from 4 minutes to several days and it takes 100% of a core. Running a listall VMs without any kind of restrictions shows the 4 user VMs in milliseconds. Is there anything specific to tags that might slow down this kind of query? Thanks Carles Figuerola
Re: VPC Private gateway not being removed
Grayson, quick stab at this: in older versions you couldn't delete a
gateway if it still had a static route on it. What version are you running
and did the gateway have a route associated?

AW: cpu overprovisioning
Dashboard is not wrong. You only have these resources left in your CS. Here is an example as far as I remember: Dashboard shows 100 GHz / 180 Ghz (cpu over provisioning is 1 / 3 Hosts each 24x 2.5Ghz) You deploy 10 vms with 1 Ghz Dashboard shows 110 Ghz / 180 Ghz (cpu over provisioning is 1 / 3 Hosts each 24x 2.5Ghz) You change cpu over provisioning to 4 Dashboard shows 440 Ghz / 720 Ghz (cpu over provisioning is 4 / 3 Hosts each 24x 2.5Ghz) You stop and start all vms Dashboard shows 110 Ghz / 720 Ghz Mit freundlichen Grüßen / With kind regards, Swen Brüseke -Ursprüngliche Nachricht- Von: Abhinandan Prateek [mailto:abhinandan.prat...@shapeblue.com] Gesendet: Mittwoch, 22.

On 22-Apr-2015, at 9:50 am, Bharat Kumar bharat.ku...@citrix.com wrote: Hi, The change in cpu overcommit factor will not change the amount of resource that are available to you. It will change the way you want to use the free resource available at that time. It won't change what was already allocated. for example if you have deployed the VMs with overcommit say 2 and after a while you change the overcommit to 3, the used resource will be scaled based on the change. changing the overcommit cannot create resource. It can only change the way you want to use the free resource. So now after the change in overcommit you can deploy 3 times more VMs (of a given service offering) than usual using the the resource that is free at the time of changing the overcommit value. The perviously allocated resource cannot be freed until you restart the VMs. This link will tell you how resource allocation calculations are made. https://cwiki.apache.org/confluence/display/CLOUDSTACK/CPU+and+RAM+Ov ercommit Thanks, Bharat.
