XenServer Site Recovery – Provide site-to-site disaster recovery planning and services for virtual environments

  • Simple and Reliable Set Up – Using the step-by-step Site Recovery wizards and StorageLink capabilities customers can quickly initiate remote data replication between arrays and automate the ongoing syncing of primary and secondary VM configurations.
  • Fast Recovery & Failback – Once the data and VM’s have been replicated to the secondary datacenter, Site Recovery provides single click failover for protected applications ensuring key IT services are back up and running quickly.
  • Unlimited Testing  – Site Recovery allows the user to stage frequent tests in an isolated virtual environment without disrupting ongoing operations. This helps to ensure disaster recovery plans remain valid.
This document describes how to configure manual DR for a XenServer Resource Pool http://support.citrix.com/article/CTX117258

Before designing any DR solution you must agree to RPO and RTO with your CEO and CFO. You also need to select the workloads and applications to protect. Consider the following:
Continuous availability is availability’s upper limit—nonstop operation through failures and outages, eliminating downtime and associated data and transaction loss.
High availability means applications remain accessible a very high percentage of the time and recover quickly from localized failures so users experience little or no interruption.
Disaster recoveryis restoration of IT services after a widespread disruption: floods, regional power interruptions or other major disasters.
  • Recovery Time Objective (RTO) – The time by which an application must recover from a failure, or maximum acceptable loss of service
  • Recovery Point Objective (RPO) – The point in time at which an application must recover, or maximum acceptable loss of data and transactions
  • Total Cost of Ownership (TCO) – The direct and indirect costs of achieving the specified RTO and RPO over an application’s lifespan (vs Risk to Business)

New improvements include:

  • Integrated vDisk Versioning
  • Automated vDisk updates
  • Support for Replicated vDisk Storage
  • XenDesktop and Streamed VM Setup Wizards

Xen 4.1 supports the following new features:

  • A re-architected XL toolstack that is functionally nearly equivalent to XM/XEND
  • Prototype credit2 scheduler designed for latency-sensitive workloads and very large systems
  • CPU Pools for advanced partitioning
  • Support for large systems (>255 processors and 1GB/2MB super page support)
  • Support for x86 Advanced Vector eXtension (AVX)
  • New Memory Access API enabling integration of 3rd party security solutions into Xen virtualized environments
  • Even better stability through our new automated regression tests

Further information can be found in the release notes.

XL Toolstack: Xen 4.1 includes a re-architected toolstack, that is based on the new libxenlightlibrary, providing a simple and robust API for toolstacks. XL is functionally equivalent and almost entirely backwards compatible with existing XM domain configuration files. The XEND toolstack remains supported in Xen 4.1 however we strongly recommend that users upgrade to XL. For more information see the Migration Guide. Projects are underway to port XCP’s xapi and libvirt to the new libxenlight library.

Credit2 Scheduler: The credit1 scheduler has served Xen well for many years.  But it has several weaknesses, including working poorly for latency-sensitive workloads, such as network traffic and audio. The credit2 scheduler is a complete rewrite, designed with latency-sensitive workloads and very large numbers of CPUs in mind. We are still calling it a prototype scheduler as the algorithm needs more work before it will be ready to become the main scheduler. However it is stable and will perform better for some workloads than credit1.

CPU pools: The default credit scheduler provides limited mechanisms (pinning VMs to CPUs and using weights) to partition a machine and allocate CPUs to VMs. CPU pools provide a more powerful and easy to use way to partition a machine: the physical CPUs of a machine are divided into pools.  Each CPU pool runs its own scheduler and each running VM is assigned to one pool.   This not only allows a more robust and user friendly way to partition a machine, but it allows using different schedulers for different pools, depending on which scheduler works best for that workload.

Large Systems: Xen 4.1 has been extended and optimized to take advantage of new hardware features, increasing performance and scalability in particular for large systems. Xen now supports the Intel x2APIC architecture and is able to support systems with more than 255 CPUs. Further, support for EPT/VTd 1GB/2MB super pages has been added to Xen, reducing the TLB overhead. EPT/VTd page table sharing simplifies the support for Intel’s IOMMU by allowing the CPU’s Enhanced Page Table to be directly utilized by the VTd IOMMU. Timer drift has been eliminated through TSC-deadline timer support that provides a per-processor timer tick.

Advanced Vector eXtension (AVX): Support for xsave and xrestor floating point instructions has been added, enabling Xen guests to utilize AVX instructions available on newer Intel processors.

Memory Access API: The mem_access API has been added to enable suitably privileged domains to intercept and handle memory faults. This extents Xen’s security features in a new direction and enables third parties to invoke malware detection software or other security solutions on demand from outside the virtual machine.

XenServer Performance and ScalabilityTesting


XenServer Scalability Configuration:

Generally speaking you should go more for a scale out scenario (higher number of VMs with lower CPU configuration) than vice versa in my experience. This is because IRQ handling in XenServer on a guest VM level is restricted to only 1 CPU. Hence if there is a log of IRQs a scaled-up VM could come to its limits. Max out hardware by higher number of VMs with lower number of vCPUs each should get better values.

Performance benchmark reports available by Cisco, HP, Dell, IBM, NetApp, EMC and Fuijts

Whatever the hypervisor XenServer, ESX 4/5, Hyper-V R2SP1, no reports of showing more than 110/120 VMs per hypervisor.

ProjectVRC – www.projectvrc.com has a number of hypervisor scalability reports created using LoginVSI the industry standard to measure user performance and the maximum amount of sessions a host can support with a decent performance.

Auto-provision of VPX / VMs on XenServer

Here is a few methods to auto-provision VMS on XenServer.. There are two methods, first is the add metadata to the VM, OVF or Template and the second is to directly read this information from XenTools commands.

Method 1:

You can add XenStore/.. metadata key value to a VM, Template or OVF. These settings are used by VPX appliance if the ns.conf does not exist.  Here is a example to Auto-provision a VPX appliance

  • Xe vm-param-set uuid=<vm uuid> xenstore-data:vm-data/ip-address=192.168.1.1 ## Needs to be done while the VM is powered
  1. Import NetScaler VPX Appliance (Do not boot)
  2. Convert this NetScaler Appliance to a XenServer Template
  3. Apply the IP details via the following commands to the Template UUID
  4. xe vm-param-add uuid=f453b65d-5d46-34b0-7efd-bef32a3484f4 param-name=xenstore-data vm-data/ip=10.0.0.10
  5. xe vm-param-add uuid=f453b65d-5d46-34b0-7efd-bef32a3484f4 param-name=xenstore-data vm-data/netmask=255.255.255.0
  6. xe vm-param-add uuid=f453b65d-5d46-34b0-7efd-bef32a3484f4 param-name=xenstore-data vm-data/gateway=10.0.0.11
  7. Quick Create VM via Template and boot up (Apply name label, networks and any other configs)
  8. xe vm-clone new-name-lablel=<name_for_clone> uuid= f453b65d-5d46-34b0-7efd-bef32a3484f4
  9. xe vm-start
  10. Shell into the NS IP and upload license files (How do you do that)? Once you obtain a license from Citrix, upload it to /nsconfig/licenses and reboot VPX. Once it’s up you should be able to enable licensed features: “enable feature NAME”

Method 2:

You can use commands provided by XenTools client on both windows and linux to read vaules in the XenStore metadata key:

Windows Command

  • “C:\Program Files\Citrix\XenTools\xenstore_client.exe” read vm-data/ip-address 192.168.1.1

Linux Commands

  • xenstore-chmod   xenstore-exists  xenstore-list    xenstore-ls      xenstore-read    xenstore-rm      xenstore-write
