The KVM Agent had two mechanisms for reporting its capabilities
and memory to the Management Server.
On startup it would ask libvirt the amount of Memory the Host has
and subtract and add the reserved and overcommit memory.
When the HostStats were however reported to the Management Server
these two configured values on the Agent were no longer reported
in the statistics thus showing all the available memory in the
Agent/Host to the Management Server.
This commit unifies this by using the same logic on Agent Startup
and during statistics reporting.
memory=3069636608, reservedMemory=1073741824
This was reported by a 4GB Hypervisor with this setting:
host.reserved.mem.mb=1024
The GUI (thus API) would then show:
Memory Total 2.86 GB
This way the Agent properly 'lies' to the Management Server about its
capabilities in terms of Memory.
This is very helpful if you want to overprovision or undercommit machines
for various reasons.
Overcommitting can be done when KSM or ZSwap or a fast SWAP device is
installed in the machine.
Underprovisioning is done when the Host might run other tasks then a KVM
hypervisor, for example when it runs in a hyperconverged setup with Ceph.
In addition internally many values have been changed from a Double to a Long
and also store the amount of bytes instead of Kilobytes.

* ipv6: Do not allow a Secondary IPv6 address to be EUI-64
EUI-64 addresses should not be allowed as they can be used in the future by a to be
deployed Instance which has to obtain this address because it matches it's MAC.
In a /64 subnet there are more then enough other IPs available to be allocated to
Instances, therefor we can safely disallow the allocation of EUI-64 addresses.

With IPv6 we are not using DHCP to allocate addresses, but using
StateLess Address Auto Configuration (SLAAC) a Instance will calculate
it's own address based on the Router Advertisements send out by the
routers in the network.
This Advertisement contains the IPv6 Subnet in use in that subnet and
allows to calculate the stable Address the Instance will obtain based
on it's MAC Address.
The existing code is 'dead code' as it has been written, but was never
used by any production code.
SLAAC only works properly with subnets of exactly 64-bits large.

* security group: Use a function to determin the physical device of a bridge
We can not safely assume that the first device listed under a bridge is the
physical device.
With VXLAN isolation a vnet device can be attached to a bridge prior to the
vxlanXXXX device being attached.
We need to filter out those devices and then fetch the physical device attached
to the bridge.
In addition use the 'bridge' command instead of 'brctl'. 'bridge' is part of the
iproute2 utils just like 'ip' and should be considered as the new default.
This command is also available on EL6 and does not break any backwards compat.

This regression was introduced with PR #2773 (Support IPv6 address in addIpToNic). The contributor did not take into consideration that the method “addIpToNic” was designed to add/allocate other IPs to a NIC. If users did not specify an IP, ACS should generate one for the network where the NIC is plugged into.
Even though I am fixing this regression here, it is still important to highlight that for IPV6, the user is not able to allocate an IP without specifying it.
It's incorrect to use the findIncludingRemovedBy and
listIncludingRemovedBy for the common list and find operation.

* vxlan: Disable IPv6 on bridge and VXLAN devices
They are only transport devices and should not be interacting
in the IPv6 traffic.
If IPv6 is enabled Instances can connect to the Hypervisor over
Link-Local IPv6 which is a potential security issue.
By disabling IPv6 on the Bridge and VXLAN device they still forward
Layer 2 packets as intended, but they do not respond on anything.
IPv4 and IPv6 traffic towards the Instances is untouched and works
as before.

* vxlan: Refactor modifyvxlan.sh for KVM by using only iproute2
This commit refactors the modifyvxlan.sh script by using only iproute2,

brctl is deprecated and most bridge functionality can be performed with
the 'ip' command.
This commit also fixes various Bash coding fixes and removes a lot of exit
status checking which was redundant.
In addition it add IPv6 underlay for VXLAN transport. If the caller (KVM Agent)
adds the '-6' flag it will generate IPv6 multicast groups and routes which will
transport the VXLAN encapsulated packaes over IPv6 multicast groups.

The static method syncVolumeToRootFolder() from VmwareStorageLayoutHelper.java:146 has been incorrectly called and leads to an infinite recursive call that ends up in a StackOverflowError. This PR fixes this.
public static void syncVolumeToRootFolder(DatacenterMO dcMo, DatastoreMO ds, String vmdkName, String vmName) throws Exception { syncVolumeToRootFolder(dcMo, ds, vmdkName, null); } -> public static void syncVolumeToRootFolder(DatacenterMO dcMo, DatastoreMO ds, String vmdkName, String vmName) throws Exception { syncVolumeToRootFolder(dcMo, ds, vmdkName, vmName, null); }
A corner case was found on 4.11.2 for #2493 leading to an infinite loop in state PrepareForMaintenance
To prevent such cases, in which failed migrations are detected but still running on the host, this feature adds a new cluster setting host.maintenance.retries which is the number of retries before marking the host as ErrorInMaintenance if migration errors persist.
How Has This Been Tested?
- 2 KVM hosts, pick one which has running VMs as H
- Block migrations ports on H to simulate failures on migrations:
iptables -I OUTPUT -j REJECT -m state --state NEW -m tcp -p tcp --dport 49152:49215 -m comment --comment 'test block migrations' iptables -I OUTPUT -j REJECT -m state --state NEW -m tcp -p tcp --dport 16509 -m comment --comment 'test block migrations
- Put host H in Maintenance
- Observe that host is indefinitely in PrepareForMaintenance state (after this fix it goes into ErrorInMaintenance after retrying host.maintenance.retries times)
This is important because it helps in communicating back the exact
error to the API callee.
Current behavior is that ParamProcessWorker#processParameters catches
the exception and returns an incorrect type exception without the
proper message.
There is no reason to not send userdata+password to the VR as all
Instances in CloudStack are Dual-Stacked. They have IPv4 and IPv6
so they can query their metadata over IPv4 at the VR.

Users reported that they weren't getting all apis listed in cloudmonkey when running a sync. After some debugging, I found that the problem is that the ApiDiscoveryService is calling ApiRateLimitServiceImpl.checkAccess(), so the results of the listApis command are being truncated because Cloudstack believes the user has exceeded their API throttling rate.
I enabled throttling with a 25 request per second limit. I then created a test role with only list* permissions and assigned it to a test user. When this user calls listApis, they will typically receive anywhere from 15-18 results. Checking the logs, you see The given user has reached his/her account api limit, please retry after 218 ms..
I raised the limit to 200 requests per second, restarted the management server and tried again. This time I got 143 results and no log messages about the user being throttled.

This increases and uses a default 15mins timeout for VR scripts and for
KVM agent increases timeout from 60s to 5mins. The timeout can
