put copy scripts in SetupCommand,
1. initiate returns host version,
2. if it doesn't match with DB, update DB, and reconnect the host.
status 9997: resolved fixed
This patch enable redundant virtual routers.
1. To enable this feature, db need to be updated using follow SQL by now(we
would get a UI way later):
UPDATE network_offerings SET redundant_router=1 WHERE guest_type="Virtual" AND
system_only=0;
2. System would try to start up two routers at different hosts. But if there is
only one host in the zone, system would start up two routers on it.
3. The failover part is using keepalived, and connection tracking part is using
conntrackd. There would be one master router and one backup router. The status
of router(master or backup) can be query from the database table domain_router
now. Management server would update the status every 30s by default.
4. The routers for the same zone would use same external NIC(same ip and mac).
The script used for fail-over would ensure only one external NIC present in the
network at any time.
5. Currently management server don't got the ability to stop one of router is
both of them reported as master. The feature is in the todo list.
After two routers start up, disconnect anyone of them, the guest network
shouldn't be affected, and established connection(http, ssh, etc.) should still
works. The fail-over on gateway part should be 3~4 seconds.
Currently the patch works with KVM. Would deal with vmware and XenServer soon.
haproxy tunning:
0. Test case:
httpd running in 5 user VMs, all of them created on a xenserver host(16 core, 42G memroy, 10G network)
domR running on an anther host with same hardware configuration.
test application, ab, running on anther host behind an anther seperate switch
1.haproxy is not a memory intensive app. I can get 4625.96 connection/s with 1G memory. While it's really a CPU intensive app, domR always uses around 100% CPU on the host.
2.By default, you can't get better connection/s rate, because ip_conntrack_max and tw_bucket are too small, you will see the error in domR like:
"TCP: time wait bucket table overflow" or "nf_conntrack: table full, dropping packet".
So I increase these numbers to 1000000 from 65536, then I can steadly get around 4600 connection/s when memory is >= 1G.
Here is the connection per second, tested by "ab -n 1000000 -c 100 http://192.168.170.152:880/test.html"
domR memory conn/s
128M: 3545.55
256M: 4081.38
512M: 4318.18
1G: 4625.96
7G: 4745.53
3. If I enable notrack for both connections between domr/user vm, and public network, that tell iptable in domR don't track the connection during my test, then I can get better number, around
5800 connections/s. But we can't enable notrack, as iptables is used to track throughput in domR.
4. In a word, with this commit, the connection rate of haproxy can be increased from 1000-2000/s to 4700/s when domR's memory is larger than 1G.
5. How many CPU need to assign to domR to get this number? Haven't finished yet, as CPU is shared by all the VMs on the host, if other VMs are busy, it will impact the performance of haproxy.
Changes specific for Xen hypervisor, and DB upgrade. Changes for vmware chcked-in already in commit 1c310a0d2ae81108386f0dd5c2e899ff00fee9e9, e71112e2f587f5d6c9c6d5337cfeb1f239f29633. KVM will not support this feature.
Changes:
- Added a new column `source_template_id` to vm_template table to carry the parent/source template ID from which the tempalte was created
- Added the column in db upgrade 224 to 225
- Changed code to save the source_template_id if there is one associated to the volume/ volume from which the snapshot was taken
- API response returns the sourcetemplateid field, if set, in all template usecases.
status 9623: resolved fixed
Also set ram_size to 1024 for console proxy offering during the upgrade

- Local fix to not log the content for ModifySshKeyCommand.
- For commands that do not want to log the parameters, added the facility to indicate this.
- For such commands, we remove the parameters from the log.
status 9336: resolved fixed
Following changes were made:
* deleteSecurityGroup/authorizeSecurityGroupIngress - removed account/domainId parameters as SG is uniquely identified by id now
* removed account_name field from securityGroup DB table; removed allowed_security_group/allowed_sec_grp_acct from security_ingress_rule.
These values were used for api response generation only for performance purposes; added caching on API level to improve performance
* Added missing security checks for securityGroups/ingressRules
Since private and public keys are logged, this is a Security concern
Changes: Added capability to 'Command' instances to support excluding certain fields from getting logged using GSON @Expose annotation.
- Update system vm_instance's template_id if it does not match the system vm template.
- Use _templateDao.findSystemVMTemplate to find the latest system vm template.
